This is a cost-effective SAW-based filtered pre-amplifier which gives excellent performance gains and improved reception on 161MHz/AIS frequencies.

New USB-C version! This pre-amp now comes with a USB-C connector and power LED!

This is a cost-effective SAW based unit which gives excellent performance gains.

All Uputronics preamps are compatible with most USB SDR Dongles such as the RTL USB, Airspy, Fun Cube. You can power them from either bias tee (this item is 100% compatible with the Airspy bias-tee) or a USB-C cable.

Bias-tee voltage input is 5V.

Note: Unlike previous models, component supply issues mean bias-tee input voltage is 5V max.

This unit is a small filter and preamp designed to go between a software-defined radio receiver and an antenna. Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. This particular model is tuned for use with 159-163MHz. To block strong commercial FM signals a high pass filter is installed before the LNA.

The LNA used is a MiniCircuits PSA4-5043+ which provides at least 20dB of gain @ 161MHz. To stop out of band intermodulation a 161MHz SAW bandpass filter, which has a 7.6MHz bandwidth, is also present. The insertion loss of this filter is approximately 1.4dB.

High-quality SMA female connectors are fitted for antenna input and radio output, a RED power indicator is provided.
