Avago Technologies Rolls Out GPS Low Noise Amplifier

Avago Technologies introduced a new miniature compact highly integrated GPS low noise amplifier (LNA).

Avago stated that its ALM-1812 integrates a LNA and pre- and post high-rejection filters in a miniature compact package to provide a complete, compact and high-performance GPS RF front-end module that will help simplify the design of a wide range of GPS handset applications. Avago is a supplier of analog interface components for communications, industrial and consumer applications.

Avago explained that the highly integrated ALM-1812 is designed for the 1.575 GHz frequency band and is housed in a miniature 4.5 by 2.2 by 1.0 mm MCOB package, reducing printed circuit board (PCB) space by more than 50 percent when compared to discreet-only solutions. The integration of FBAR filtering enables the ALM-1812 to reach more than 90 dBc of Cell/PCS-band rejection. Additionally, this GPS LNA effectively leverages Avago's 0.25 um GaAs enhancement-mode pHEMT process to deliver a 1.66 dB noise figure, 18.5 dB gain, and +2 dBm input third order intercept point (IIP3) at typical operating conditions of 2.7V and 6 mA.

Simultaneous GPS (S-GPS), and other location-based GPS services, require a high level of receiver sensitivity. Avago said its ALM-1812 delivers a very low noise figure and high linearity which helps to improve the sensitivity of GPS applications. Additionally, the integrated FBAR filter offers rejection at Cell/PCS-band frequencies and WiFi/Bluetooth, which makes it a device to help improve the performance of GPS receivers for S-GPS operation in handsets. In addition, the ALM-1812 has a built-in shunt inductor at the RF input pin to enhance ESD production. By integrating a GPS LNA with pre- and post high-rejection film bulk acoustic resonator (FBAR) filters, Avago reported that the ALM-1812 simplifies and shortens the RF design process, reduces component count and provides RF performance levels that are critical in the use of GPS applications.

ALM-1812 samples and production quantities are available now through Avago's direct sales channel and distribution partners.
