Low Noise Ampli er
SPECTRUM MICROWAVE
P/N: 310-024107-021
For GPS Applications
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 3-pole ceramic filter selects only the desired GPS
positioning signal 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.
