BGM1043N7 Introduction 2 Introduction Global Navigation Satellite System or GNSS receiver, as we know, works on the reception of location based information from satellite signals. There are several standards worldwide like GPS, GLONASS, Galileo and COMPASS Bei Du. However, the power levels of the satellite signals received, can be lower than -130 dbm. This poses a challenge on the sensitivity of the GNSS receiver. Along with this, the ever growing disturbing or jamming signals in the adjacent cellular bands makes the design of the receiver front-end even more difficult. The rapidly growing market for GNSS systems is driving the design of advanced and high-performance GNSS receivers. A simple overview of the GNSS RF system in a mobile phone or other handheld devices is shown in Figure 2. Mobile Phone / Handheld device Satellite GNSS signal Tranceiver module GSM800/GSM900/ DCS/PCS1800/ UMTS/ WLAN Tx Signal GNSS Receiver IC Int. LNA GNSS RF Front-end module ESD protection GNSS Signal < -130dBm Blocking Signal Figure 2 RF System Overview: Mobile Phone GNSS receivers for mobile or handheld applications are always under the threat of high power cellular signals. Due to the coexistence of GNSS and Cellular services, there is a strong coupling of the DCS/PCS and Cellular signals to the GNSS receiver. The performance of a standard integrated GNSS receiver chip cannot meet the specifications required for the present systems. An external RF front-end is essential to achieve this required performance. The most important prerequisites for the front-end of a GNSS receiver are low noise figure and sufficient amplification of the desired signal together with high attenuation of the jamming signals. Application Note AN283, Rev. 1.0 6 / 23

BGM1043N7 2.1 Systems overview of a GNSS receiver Several configurations can be adopted for a GNSS receiver chain. In all configurations, as mentioned earlier, a RF front-end like BGM1043N7 is placed between the antenna and the GNSS receiver chip. Mobile/portable devices as well as personal navigation devices request decreasing form factor used by the implementation of the GNSS function in the devices. BGM1043N7 supports the designers to minimize the area in the front-end. Such a configuration is shown in Figure 3. The BGM1043N7 can also be used for the active antenna module.

BGM1043N7 Description 3 Description The BGM1043N7 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 BGM1043N7 provides 15.1 db gain, 1.5 db noise figure and high linearity performance. In addition BGM1043N7 provides very high out-of-band attenuation in conjunction with a high input compression point. It can withstand IEC61000-4-2 ESD contact discharge at the RF input as high as 6 kv in the application circuit shown in Figure 5. Its current consumption is as low as 4.0 ma. It operates over the 1.5 V to 3.6 V supply voltage range. Figure 4 Block Diagram of BGM1043N7 Application Note AN283, Rev. 1.0 8 / 23

BGM1043N7 Application Circuit and Block Diagram 4 Application Circuit and Block Diagram The BGM1043N7 is internally matched at the output to 50 Ohm. The LNA bias circuitry is also integrated on chip. Therefore, only three external components are required in the application.
