Infineon公司的BGM1033N7是集成了低插入損耗前置濾波器和高性能低噪音放大器(LNA)的前端模塊,主要用在GPS和格羅納斯(Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS ))衛(wèi)星系統(tǒng). 工作頻率1575.42 MHz 和598.06-1605.38 MHz,增益14.8dB,噪音1.65dB,工作電壓1.5V-3.6V,電流損耗4.0mA.本文介紹了BGM1033N7主要特性,方框圖,應(yīng)用電路圖及應(yīng)用電路中元件數(shù)值表, 手機(jī)RF系統(tǒng)框圖和手機(jī)和PND的GPS系統(tǒng)框圖以及評(píng)估板. 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應(yīng)用: - Global Positioning System (GPS) - GLONASS (Russian GNSS)
