CHARACTERISTICS

Table 1

Bandwidth 40 to 860 MHz; VB = 24 V; Tcase =30 °C; ZS =ZL =75 Ω

Notes

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

fq = 805.25 MHz; Vq = 44 dBmV;

measured at fp +fq = 860.5 MHz.

2. Measured according to DIN45004B:

fp = 851.25 MHz; Vp =Vo;

fq = 858.25 MHz; Vq =Vo −6 dB;

fr = 860.25 MHz; Vr =Vo −6 dB;

measured at fp +fq − fr = 849.25 MHz.

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