Description
Details
A high-quality, high-performance, complete LNA & SAW filter module for Inmarsat at a very affordable price.
The module should be powered via low-noise bias-tee which supplies between 3.0V-5.5V. The bias tee must be capable of supplying a minimum of 35mA of current.
As with all other high-frequency applications, we recommend using in conjunction with an SDR specifically designed for long-term, high-frequency performance without degradation, such as the NESDR SMArTee XTR. or a HackRF.
The center frequency of the module is 1.542GHz with approximately 80MHz of bandwidth (-6dB rolloff). As such, it should be used for reception of frequencies between 1.50GHz-1.58GHz.
The LNA is a dual-stage design with a very low noise figure of 1dB (nominal).
4 mounting holes are available on the PCB for various mounting options. The input and output connectors are female SMA.

- For Inmarsat, EGC, SafetyNet and JAERO, but Outernet movedReview by WA4OSH

The LNA/SAW filter well for Outernet while the service was still on L-Band using the Inmarsat satellites. At the time, I was using an 8 dBi 3-element patch antenna and an RTL-SDR receiver. Outernet has since moved to the Ku-Band, so this device is no longer applicable for that application.Quality Performance Value
The LNA may still useful for those wishing to build a receiver for EGC, SafetyNet and JAERO messages.

This is very good LNA. My outernet system is ok. (Posted on 10/1/2017)Performance Value Quality - Perfect LNA with one small demandReview by Bernard

I bought this LNA to receive Inmarsat here in Western Europe, which works very well. Now I've ordered a second one on Amazon to be connected inline to the first. It's a pity that it seems not to work because the 5 Volt of the bias is not switched to the antenna side. (Posted on 6/8/2017)Quality Performance Value
