915 MHz Filter/Preamp with TX BYPASS
This 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.
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
Uputronics filtered preamps for improved reception on 978Mhz (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 mini cable (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 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. Connectors are SMA female both sides.

Airspy HF+ Discovery SDR
Building on the field-proven Airspy HF+ architecture, we designed the Most Refined HF/VHF SDR with world class performance in the smallest form factor.
The Airspy HF+ Discovery sets a new standard in terms of reception performance with extra pre-selectors for all the supported bands and a New DSP Core to optimize the gain distribution and the filtering parameters in real-time and dig deeper in the noise.
The signal path includes very high dynamic range data converters along with high performance passive mixers with an excellent Polyphase Harmonic Rejection structure. The included band-tracking pre-selectors eliminate unwanted interference and preserve the dynamic range of the receiver. With its world class strong signal handling capability and incredibly Low Noise, the HF+ Discovery is the ideal companion for All your High Performance Receive Scenarios.
Both the architecture and level of integration achieved in this design allow us to bring top performance reception at a very affordable price.
All the major SDR software is supported. Check the download page.Ready to discover all these signals hiding in your spectrum?
