PRODUCT OVERVIEW

This is a small, pre-filtered GPS L1 Low Noise Amplifier centered at 1575.42 MHz with a typical gain of 21 dB in the pass band. This product has excellent out-of-band rejection specifications, provides power handling of up to a maximum +10 dBm. The current consumption is low, at only 20 mA. Multiple power-up options: USB and DC header. Built-in Input bias tee enables powering of active antenna. 

Note that +5 VDC will appear at RF input terminal. This is only used to power an active antenna or another LNA upstream with a bias-tee. Please ensure that all sources connected to RF input are protected from DC.

APPLICATIONS

• GPS L1 signal reception in a weak signal environment
• Rejection of strong signals in Cellular, LTE, UHF and 915 MHz, 2.4 GHz ISM bands
• GPS signal processing
