DESCRIPTION
Hybrid amplifier modules for CATV
systems operating over a frequency
range of 40 to 450 MHz at a voltage
supply of (DC). The BGY80 is
intended for use as a 12.5 dB
pre-amplifier and the BGY81 as a
12.5 dB final amplifier.

Notes
1. fp = 55.25 MHz; Vp = 46 dBmV; fq = 391.25 MHz; Vq = 46 dBmV; measured at fp + fq = 446.5 MHz.
2. Measured according to DIN45004B: fp = 440.25 MHz; Vp = Vo; fq = 447.25 MHz; Vq = Vo −6 dB; fr = 449.25 MHz;
Vr = Vo −6 dB; measured at fp + fq − fr = 438.25 MHz.
3. The modules normally operate at VB = 24 V, but are able to withstand supply transients up to 30 V.
