Description
2 Description
The BGM781N11 is a combination of a low-insertion-loss pre-filter with Infineon’s high performance low noise
amplifier (LNA) and a high-attenuation post-filter for Global Positioning System (GPS) applications. 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.
