Infineon BGM1033N7 GPS和GLONASS前端模块解决方案

Infineon公司的BGM1033N7是集成了低插入损耗前置滤波器和高性能低噪音放大器(LNA)的前端模块,主要用在GPS和格罗纳斯(Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS ))卫星系统. 工作频率1575.42 MHz 和598.06-1605.38 MHz,增益14.8dB,噪音1.65dB,工作电压1.5V-3.6V,电流损耗4.0mA.本文介绍了BGM1033N7主要特性,方框图,应用电路图及应用电路中元件数值表, 手机RF系统框图和手机和PND的GPS系统框图以及评估板.

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
