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 are able to withstand supply transients up to VB = 30 V.
