BGY588

Table 2

Bandwidth 40 to 450 MHz; Tcase =35 °C; ZS =ZL =75 Ω

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 = 66.5 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.
