CATV ampliﬁer module

BGY89

CHARACTERISTICS

Bandwidth 40 to 450 MHz; VB = 24 V; Tmb = 35 °C; ZS = ZL = 75 Ω.

Notes

1. fp = 55.25 MHz; Vp = 46 dBmV;

fq = 343.25 MHz; Vq = 46 dBmV;

measured at fp + fq = 398.5 MHz.

2. Measured according to DIN45004B:

fp = 440.25 MHz; Vp = Vo = 63 dBmV;

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