Uputronics wide band low noise pre amps covering 100MHz to 4Ghz.


This is a cost effective wide band 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) LNA kit is fitted which takes it to 26V.


This unit is a small filter and preamp designed to go between a software defined radio receiver and an antenna.

The LNA used is a MiniCircuits PSA4-5043+ gain at common frequencies:


90MHz
24db
145MHz
23.9db
434Mhz
21.7db
868MHz
18db
1090MHz
16.7db
1415MHz

 Connectors are SMA female both sides.
