Notes
1. fp = 483.25 MHz; Vp = Vo;
fq = 490.25 MHz; Vq = Vo −6 dB;
fr = 492.25 MHz; Vr = Vo −6dB;
measured at fp + fq − fr = 481.25 MHz.
2. fp = 851.25 MHz; Vp = Vo;
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.
