GPS LNA First To Integrate High Rejection FBAR Filter

The ALM-1612 embarks as the industry’s first high-gain GPS low-noise amplifier (LNA) with an integrated, high-rejection FBAR filter. Under typical operating conditions of 2.7V and 6 mA, the LNA/filter module delivers a 0.9-dB noise figure, an 18-dB gain, a +2-dBm input third order intercept point, and greater 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. Available in a 3.3 mm x 2.1 mm x 1 mm MCOB package, the device provides a CMOS-compatible shutdown pin to turn the LNA on/off or to adjust the variable current and a shunt indicator at the RF-input pin enhances its ESD protection. Allegedly, the ALM-1612 can operate at voltages as low as 1.8 V and still achieve low-noise figures and high gain. Pricing begins at $1.31 each/10,000. AVAGO TECHNOLOGIES, San Jose, CA.
