Through the low insertion loss of the filters, the BGM781N11 provides 18.6 dB gain, 1.7 dB noise figure and high linearity performance. In addition BGM781N11 provides very high out-of-band attenuation in conjunction with a high input compression point. Its current consumption is as low as 3.3 mA. It operates over the 1.5 V to 3.6 V supply voltage range.
