CATV ampliﬁer module

BGY68

CHARACTERISTICS

Table 1

Bandwidth 5 to 75 MHz; VB = +24 V; Tmb =30 °C; ZS =ZL =75 Ω

Notes

1. fp = 19 MHz; Vp = 50 dBmV;

fq = 31 MHz; Vq = 50 dBmV;

measured at fp +fq = 50 MHz.

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