Filtered amp improves GPS reception
GPS low noise amplifier with integrated filter provides superior reception sensitivity and is ideal for use in handsets, in-vehicle navigation GPS receivers and GPS antennas.
Avago Technologies has announced the industry's first GPS low noise amplifier (LNA) with integrated filter With a very low noise figure and high linearity, Avago's ALM-1412 provides superior GPS signal reception sensitivity and is ideal for use in handsets, in-vehicle navigation GPS receivers and GPS antennas

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
In particular, the ALM-1412 provides excellent noise rejection at cellular/PCS-band frequencies, a critical feature for simultaneous GPS (S-GPS) operation.
Designers of handsets or in-vehicle navigation can create compact products with more features and functionality due to the very small package size of the ALM-1412.
Avago has integrated its GPS LNA with its FBAR (film bulk acoustic resonator) filter into a 3.3 x 2.1 x 1.1mm MCOB package, which reduces PCB space and component count for GPS applications at 1.575GHz.
A built-in shunt inductor included at the RF input of the LNA enhances ESD protection.
During typical operating conditions of 2.85V and 8mA, the ALM-1412 delivers an exceptional 0.85dB noise figure, 12.5dB gain, +6.6dBm IIP3 (input third order intercept point) and 58dBc cell and PCS-band rejection.
The ALM-1412 can also operate at 1V and still achieve very low noise figure and high gain, making it suitable for use in critical low-power GPS applications or during low-battery situations.
Samples are available now.
Production quantities will be available at the end of March 2007 through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
