Low Noise Ampliꢀer

SPECTRUM MICROWAVE

P/N: 310-025103-022

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.

P/N: 310-025103-022

Typical Performance Speciꢀcations

Frequency. . . . . . . . . . . . . 1575.42 MHz (L1)

1227.60 MHz (L2)

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.

Bandwidth . . . . . . . . . . . . 30 MHz min.

Noise ꢀgure . . . . . . . . . . . 2.5 dB max.

VSWR . . . . . . . . . . . . . . . 1.5:1 max.

Gain . . . . . . . . . . . . . . . . 14 dB min.

Gain Flatness . . . . . . . . . . +/-0.5 dB

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.

Rejection . . . . . . . . . . . . . 40 dB @ 1050, 1410, 1710 MHz

Bias . . . . . . . . . . . . . . . . . Ext Bias, MR01

DC Power . . . . . . . . . . . . 16-32 VDC
