Low Noise Ampli er

SPECTRUM MICROWAVE

P/N: 310-025103-012

For GPS Applications

1227 MHz/1575 MHz

This series of Low Noise Amplifiers provides a filtered,

low-noise gain solution ideal for applications where higher

reliability is critical. These filtered low noise amplifiers are

designed to reduce out-of-band interference while achieving

high dynamic range.

A pair of diplexed 3-pole ceramic filters select only the

desired GPS signals while the low-noise gain stage

maintains the receiving system’s sensitivity.

The LNA rejects undesired signals by at least 40 dB at

1050, 1410, and 1710 MHz. See the graphs on Page 2

for return loss, rejections, and gain of a typical unit.

The preamplifier is powered by DC voltage applied to

the center conductor of the output connector. Optionally,

the unit can be powered through an external DC bias

connector.
