Notes
1. fp = 349.25 MHz; Vp = 59 dBmV;
fq = 403.25 MHz; Vq = 59 dBmV;
measured at fp + fq = 752.5 MHz.
2. Measured according to DIN45004B:
fp = 851.25 MHz; Vp = Vo = 59 dBmV;
fq = 858.25 MHz; Vq = Vo −6 dB;
fr = 860.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 849.25 MHz.
3. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
