BGY787

750 MHz, 21.5 dB gain push-pull ampliﬁer

[1]

fp = 55.25 MHz; Vp = 44 dBmV; fq = 691.25 MHz; Vq = 44 dBmV; measured at fp +fq = 746.5 MHz.

[2]

Measure according to DIN45004B;

fp = 740.25 MHz; Vp =Vo; fq = 747.25 MHz; Vq =Vo − 6 dB; fr = 749.25 MHz; Vr =Vo − 6 dB; measured at fp +fq − fr = 738.25 MHz.

[3]

The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
