CATV ampliﬁer module

BGY683

CHARACTERISTICS

Bandwidth 40 to 600 MHz; VB = 24 V; Tcase = 30 °C; ZS = ZL = 75 Ω.

Notes

1. fp = 55.25 MHz; Vp = 44 dBmV;

fq = 541.25 MHz; Vq = 44 dBmV;

measured at fp + fq = 596.5 MHz.

2. Measured according to DIN45004B:

fp = 590.25 MHz; Vp = Vo;

fq = 597.25 MHz; Vq = Vo −6 dB;

fr = 599.25 MHz; Vr = Vo −6 dB;

measured at fp + fq − fr = 588.25 MHz.

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