Low Noise AmplifiersLNA-GPS line amp

Low Noise Amplifier / Preamplifier for the 1575 MHz GPS band

Description

Miniature GPS line amplifier.
Suitable for GPS signal distribution network.
Built-in band-pass filter to attenuate unwanted signals and clean up the distributed GPS signal.
Low input and output VSWR.
Low noise figure.
Low weight.
Wide temperature range.
Wide supply voltage range.
Low power consumption.
DC supplied from phantom voltage on the signal line.
Also exists with a DC block on the input.
Also available with DC-path from output to input to DC-feed an active GPS antenna or to DC feed more amplifiers in series on the same line.

Application Example 1:

How to connect the LNA-GPS line amp-SMA-SMA as preamplifier for a passive GPS antenna to compensate high loss in long coax cable downleads.

DC supply voltage is inserted on the signal line at the GPS receiver by the junction box JB1-1G (to be ordered separately).
