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) 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.

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	15.2db

 Connectors are SMA female both sides.
