ALM-2203

SDARS LNA Module

Product Brief

Description

Avago Technologies’ALM-2203 is an ultra low-noise front-

end module that combines three low-noise amplifiers

(LNA) with a Film Bulk Acoustic Resonator (FBAR) filter into

a 5mm x 5mm Molded Chip On Board (MCOB) package

for use in Satellite Digital Audio Radio Service (SDARS) ra-

dios. The LNAs use Avago Technologies’ proprietary GaAs

Enhancement-mode pHEMT process to achieve high gain

with very low noise figure and high linearity. Noise figure

distribution is very tightly controlled. The integrated filter

utilizes an Avago Technologies’ leading-edge FBAR filter

for exceptional rejection.

The low noise figure and high gain, coupled with low cur-

rent consumption make it suitable for use in critical low-

power SDARS applications.
