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: 310-025107-011
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 . . . . . . . . . . . 2.0 dB max.
VSWR . . . . . . . . . . . . . . . 1.5:1 max.
Gain . . . . . . . . . . . . . . . . 34 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 . . . . . . . . . . . . . . . . . Coaxial Bias
DC Power . . . . . . . . . . . . 5-16 VDC
