The BGM1033N7 is a combination of a low-insertion-loss pre-filter with Infineon’s high performance low noise amplifier (LNA) for Global Positioning System (GPS) and Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) applications. Both, GPS and GLONASS frequency bands, can be used at the same time. Through the low insertion loss of the filter, the BGM1033N7 provides 14.8 dB gain, 1.65 dB noise figure and high linearity performance. In addition BGM1033N7 provides very high out-of-band attenuation in conjunction with a high input compression point. It can withstand IEC ESD contact discharge at the RF input as high as 6 kV. Its current consumption is as low as 4.0 mA. It operates over the 1.5 V to 3.6 V supply voltage range. BGM1033N7主要特性: • Operating frequencies: 1575.42 MHz and 1598.06-1605.38 MHz • High Gain: 14.8 dB • Low Noise Figure (GPS): 1.65 dB • Low current consumption: 4.0 mA • Out-of-band rejection in cellular bands: > 43 dBc • Input compression point in cellular bands: 30 dBm • Supply voltage: 1.5 V to 3.6 V • Tiny TSNP-7-10 leadless package (2.3 x 1.7 x 0.73 mm3) • RF output internally matched to 50 Ω • IEC ESD contact discharge of RF input pin: 6 kV • Only 3 external SMD parts • RoHS compliant package (Pb-free) BGM1033N7应用: - Global Positioning System (GPS) - GLONASS (Russian GNSS)  图1.带外接元件的BGM1033N7方框图  图2.
