PRODUCT OVERVIEW

This is a small, Pre-Filtered GNSS Low Noise Amplifier. It covers the following technologies:

• GPS L1-L5
• BeiDou COMPASS
• GLONASS
• NAVIC

The LNA has an average gain of 27 dB in the pass band and Noise Figure of 1 dB. This product has excellent out-of-band rejection specifications, provides power handling of up to a maximum -15 dBm and has an operating temperature range of -40C to +85C. The part can be powered using either a micro-USB cable, providing +5V to the header or DC on the RF output as it has a built-in Bias Tee.

Please note the following precaution since the Bias Tee is installed. When powering the device using either the DC header or the USB connector, +5 VDC will appear on the RF output. If your receiver does not have a DC blocking capacitor on its input or some other form of DC voltage protection, this voltage WILL damage your receiver.

APPLICATIONS

• GNSS signal reception in a weak signal environment

• Rejection of strong signals in Cellular, LTE, UHF and 915 MHz, 2.4 GHz ISM bands

• GNSS signal processing
