This product from our friends at Uputronics is a cost effective SAW based filter and amplifier which give excellent performance gains.
It is compatible with our dAISy, dAISy 2+ and dAISy HAT AIS Receivers, extending their range in most situations. In addition, this preamp is also compatible with most USB SDR Dongles such as the RTL USB, Airspy, Fun Cube.
This unit is a filter and preamp designed to go between an AIS receiver or SDR receiver and an antenna. It is powered from a USB mini cable, which is included. We also offer various useful adapters and cables as options.
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.
