ALM-1612 LNA/filtermodule

Avago Technologies has introduced its next-generation high-gain GPS low noise amplifier (LNA) with integrated filter. Under typical operating conditions of 2.7 V and 6mA, the ALM-1612 LNA/filter module delivers a 0.9 dB noise figure, 18 dB gain, +2 dBm input third order intercept point and more than 65 dBc of cell/PCS-band rejection. Designed for the 1.575 GHz frequency band, the ALM-1612 targets GPS handset, recreational, in-vehicle navigation and antenna markets.

Packaged in a 3.3 x 2.1 x 1.0 mm miniature MCOB package, the ALM-1612 is integrated with Avago's FBAR filter for superior rejection at cell/PCS band frequencies. 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. The device can also operate at low voltages of 1.8 V and still achieve very low noise figures and high gain.

Pricing for the ALM-1612 begins at Rs.56.14 ($1.31) in 10,000 piece quantities. The new amplifiers are available now through Avago's worldwide distribution partners.
