Avago's GPS Low Noise Amplifier has Integrated FBAR Filter

(Product News, 3 Sep 2008)

Avago Technologies has launched ALM-1612—its next-generation high-gain GPS low noise amplifier (LNA) with integrated filter rated at 2.7V, and 6mA. The LNA/filter module delivers exceptional performance levels, including a 0.9dB noise figure, 18dB gain, +2dBm input third order intercept point and more than 65dBc of cell/PCS-band rejection.

Designed for the 1.575GHz frequency band, the ALM-1612 targets GPS handset, recreational, in-vehicle navigation and antenna markets. The device comes in a 3.3x2.1x1mm miniature MCOB package, and integrates Avago's FBAR filter for superior rejection at cell/PCS band frequencies, which is particularly critical for simultaneous GPS operation in handsets and other mobile applications.

The ALM-1612 provides a CMOS-compatible shutdown pin to turn the LNA on/off or to adjust the variable current. A built-in shunt indicator at the RF input pin of the LNA enhances its ESD protection. Avago's ALM-1612 can also operate at 1.8V and still achieve very low noise figures and high gain, making it ideal for use in low-power GPS applications, such as handsets and portable GPS navigation devices.
