Notes
1. fp = 55.25 MHz; Vp = 44 dBmV;
fq = 493.25 MHz; Vq = 44 dBmV;
measured at fp + fq = 548.5 MHz.
2. Measured according to DIN45004B:
fp = 540.25 MHz; Vp = Vo;
fq = 547.25 MHz; Vq = Vo −6 dB;
fr = 549.25 MHz; Vr = Vo −6 dB;
measured at fp + fq − fr = 538.25 MHz.
3. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
