Avago Technologies has announced two ultra-low noise, high gain, high linearity gallium-arsenide balanced amplifiers for cellular infrastructure applications.

Avago's MGA-16516/17516, which are the latest additions to its family of economical, easy to use LNAs, helps to improve the sensitivity and dynamic range of cellular infrastructure applications.

Both LNAs feature a compact footprint and are designed to be used as first-stage LNAs.

Typical applications include cellular base-station transceiver radio cards, tower-mounted amplifiers, combiners, repeaters and remote/digital radio heads.

Avago's MGA-16516/17516 LNAs are housed in a 4 x 4 x 0.85mm surface-mount 16-lead QFN package, and were developed using Avago's 0.25mm GaAs enhancement-mode pHEMT process.

The MGA-16516 operates from 500-1,700MHz, while the MGA-17516 operates from 1,700-2,700MHz.

These LNAs will enable Avago to provide support for GSM, CDMA, UMTS and next-generation LTE cellular bandwidths.

The MGA-16516/17516 have been designed to be used with 3dB hybrid couplers at the input and output of LNAs typically found in the front end of cellular base stations, combiners and transceiver radio cards.
