Uputronics filtered preamps for improved  reception on 161MHz/AIS frequencies.

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

All our 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 simple USB minicable (Not Supplied). Bias tee/USB voltage is 5V max unless the optional (see related items) LDO kit is fitted which takes the bias-tee voltage input range from 5V to 26V (USB remains 5V)

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 an 161MHz SAW bandpass filter, which has a 7.6MHz bandwidth is also present. The insertion loss of this filter is approximately 1.4dB.  Connectors are SMA female both sides.

See related items for a suitable USB Type A to Mini B Cable to power the unit.
