Introduction
1.1 Purpose
The TRF2436 EVM provides a platform for evaluating the TRF2436 high-power, dual-band RF front-end
under various signals, reference, and supply conditions. Use this document with the EVM schematic
diagram supplied. Using the TRF2436EVM, you can rapidly evaluate the TRF2436 with a minimum of
manual setup.
1.2 System Requirements
Use the following equipment when evaluating the TRF2436EVM:
•
•
+3.3-V power supply, 800 mA.
Signal generator: Agilent ESG Series (with baseband I/Q modulation option for modulated testing) or
equivalent.
•
•
Spectrum analyzer: Agilent PSA Series (with phase noise option) or equivalent.
Vector signal analyzer: Agilent 89600 Series for 802.16x modulated EVM testing or equivalent.
1.3 Power Requirements
The demonstration board requires only one supply for proper operation. Connect +3.3 V at P1 and the
return to P2. Always terminate active PA outputs before enabling the power supply.
Voltage Limits
Exceeding the maximum input voltages can damage EVM components. Undervoltage can cause improper
operation of some or all of the EVM components.

Physical Description
2.2 RX Operation
1. Set TR (J13) to logic 0.
2. Set PA_A SEL (J10) to logic 0.
3. Connect a differential LO source to the LOP/LON SMAs (or use an external balun).
Set the LO to an appropriate frequency, with the power level between 0 to +4 dBm. Remember that for
A-band operation, the LO input frequency is doubled inside the TRF2436; so, the LO should be set to
half the frequency desired at the mixer LO port.
4. For mixer stage measurement:
a. Terminate RFA (J9) and RFANTA (J6) into 50 Ω.
b. Connect an RF source to MFA (J8). Set to a desired RF frequency and typical power level
of –20 dBm.
c. Connect a spectrum analyzer to the IF (J7) output.
d. Turn on the 3.3-V power supply (~90 mA).
e. Observe the IF output on a spectrum analyzer (374 MHz).
5. For LNA stage measurement:
a. Terminate IF (J7) and MFA (J8) into 50 Ω.
b. Connect an RF source to RFANTA (J6). Set to a desired frequency and typical power
level of –40 dBm.
c. Connect a spectrum analyzer to RFA (J9).
d. Turn on the power supply.
e. Observe the LNA output on a spectrum analyzer.
f. Use jumper J14 (RXDGC) to select between LNA high (pins 2-3) and low gain (pins 1-2)
modes.

EVALUATION BOARD/KIT IMPORTANT NOTICE
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. Persons handling the
product(s) must have electronics training and observe good engineering practice standards. As such, the goods being provided are
not intended to be complete in terms of required design-, marketing-, and/or manufacturing-related protective considerations,
including product safety and environmental measures typically found in end products that incorporate such semiconductor
components or circuit boards. This evaluation board/kit does not fall within the scope of the European Union directives regarding
electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the
technical requirements of these directives or other related directives.
Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30
days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY
SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to
take any and all appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of
patents or services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 0 V to 3.3 V and the output voltage range of 0 V to 3.3 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 85°C. The EVM is designed to
operate properly with certain components above 85°C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements,
improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.
Customers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s
standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this
warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily
performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such
