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 passband. This module 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. This module has two different power-up options: USB, DC header.

BIAS TEE OPERATION

Please note that the Bias Tee is on the input and so it can only be powered by DC voltage between 2.5V and 5.5V on the header or USB. See the figure in the product pictures to see how this would work. Use this product if you want to power an active antenna. If instead you're looking for a GPS LNA that can be powered by DC over the RF cable that connects to the GPS receiver then use this product instead.

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
