Small RF front-end module from Infineon for GPS apps

Infineon has introduced the BGM781N11, a new small GPS receive front-end module that integrates one GPS Low Noise Amplifier (LNA) and two Surface Acoustic Wave (SAW) filters with high electrostatic discharge (ESD) for Global Positioning System (GPS) applications such as mobile phones, personal navigation devices and other handheld systems.

The key features of the BGM781N11 device are,

1575.42 MHz of operating frequency
18.6 dB of high gain
Low noise figure of 1.7 dB
Low current consumption of 3.3 mA
80 dBc of out-of-band rejection in cellular bands
20 dBm of input compression point in cellular bands
RF input internally pre-matched to 50 Ohm
RF output internally matched to 50 Ohm
2 kV of HBM ESD capability of all pins
8 kV of IEC ESD contact discharge of RF input pin
Only 2 external SMD parts
RoHS compliant package (Pb-free)

With the BGM781N11 only two external passive components are required in a GPS application, which minimizes the PCB space. In addition, the BGM781N11 has low power consumption of 5.94 mW, and supports a power supply range between 1.5V and 3.6V.

"Market experts expect GPS to further penetrate all kinds of applications and devices and to be featured in at least one third of all mobile phones to be produced in 2011, becoming a standard feature for the next generations of mobile phones," said Michael Mauer, Senior Marketing Director, RF and Protection Devices at Infineon Technologies. "Infineon is committed to continue developing a strong portfolio of completely integrated, high-performance GPS receive front-end modules. With the GPS receive front-end module BGM781N11 Infineon underlines our leading position in the GPS market."
