Notes  
1. fp = 55.25 MHz; Vp = 46 dBmV;  
fq = 343.25 MHz; Vq = 46 dBmV;  
measured at fp + fq = 398.5 MHz.  
2. Measured according to DIN45004B:  
fp = 440.25 MHz; Vp = Vo = 63 dBmV;  
fq = 447.25 MHz; Vq = Vo 6 dB;  
fr = 449.25 MHz; Vr = Vo 6 dB;  
measured at fp + fq - fr = 438.25 MHz.  
3. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
