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. 1995 Nov 09 3, BGE885123456789C1 C4 12 V input output R C2 C3 VB = 24 V MGD013 Pins 1 and 9 carry DC voltages.
