915 MHz Filter/Preamp
$52.95NOT SUITABLE FOR HELIUM CRYTOMINING (No TX Bypass)
Uputronics filtered preamps for improved reception on 915 Mhz.
This is a cost effective SAW based unit which give excellent performance gains.
All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB minicable (Purchased separately). Bias tee/USB 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. 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 16dB of gain. To stop out of band intermodulation a 915 Mhz SAW bandpass filter, which has a 15MHz bandwidth is also present. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB. Connectors are SMA female both sides.
The connectors on both input and output are SMA Female. The external power connector is a USB-C and this revision has a power LED.

915 MHz Filter/Preamp with TX BYPASS
$99.95This preamp IS suitable for helium cryptomining (it has a TX Bypass)
Uputronics filtered preamps for improved reception on 915Mhz WITH TX BYPASS.
This unit is a filtered preamp designed to go between a radio transceiver and an antenna which gives excellent performance gains for reception and bypasses the preamplification circuit when a transmission is detected.
Power is either via bias tee or a USB-C cable (Not Supplied – See related items for a suitable USB Type A to C Cable). Bias-tee voltage input is 5V.
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. These particular models are tuned for use with frequencies centred on 915MHz (893MHz-935MHz). The LNA provides around 15dB of gain at 915MHz.
SMA female connectors are fitted for antenna input and radio output, a blue power indicator is provided which switches to red to indicate the unit is bypass mode. The external power connector is a USB-C.
Max TX power +15dBm (30mW)
TX detection threshold -5dBm (+/-2dBm)Data Sheet Here : https://store.uputronics.com/files/FPA-TXB-V6.03.pdf

978 MHz UAT Filter/Preamp
$52.95Uputronics filtered preamps for improved reception on 978 Mhz (UAT).
This is a cost effective SAW based unit which give excellent performance gains.
All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB minicable (Purchased separately). Bias tee/USB voltage is 5V max.

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 13dB of gain. To stop out of band intermodulation a 978Mhz SAW bandpass filter, which has a 15MHz bandwidth is also present. The insertion loss of this filter is approximately 2.3dB, which does increase the overall noise figure of the unit to 0.75dB.
