PRODUCT OVERVIEW

This is a small, Pre-Filtered GPS L1 Low Noise Line Amplifier centered at 1575.42 MHz with a typical gain of 21 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.

It can be placed inline between a GPS receiver and a passive antenna.

If you're looking for an inline amplifier that passes DC through to the active antenna - use this GPS LNA with DC bypass instead.

This amplifier is powered by a DC from a GPS receiver or a GPS Bias Tee. Note: This LNA requires +3.3V / 120 mA 

You can power it in your lab using the USB port or DC header but note ⚠️  A DC voltage (same as that applied) will be on the RF output ports.

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 L1 signal processing 

KEY SPECIFICATIONS OVERVIEW

• Gain of 21 dB is in the sweet spot for GPS systems - used to boost extremely weak satellite signals before they are degraded by cable loss, filters, and receiver electronics 
• Noise figure of less than 1 dB (typically 0.8 dB). This improves GPS sensitivity, increases carrier-to-noise ratio, and allows the receiver to detect satellites faster and in weaker signal conditions.
• The IP3 specification (+29 dBm) differentiates this LNA from others on the market. High IP3 amplifiers handle strong nearby signals without generating distortion.
