## Description

The Uputronics 868MHz SDR Filtered Preamp combines a SAW bandpass filter and low-noise amplifier to dramatically enhance reception quality for software-defined radio applications. This precision-engineered device effectively eliminates out-of-band interference while providing additional gain, making it an invaluable tool for receiving FLARM, LoRa, and ISM band signals with exceptional clarity.

Key Features- MiniCircuits PSA4-5043+ LNA providing 16dB gain at 868MHz
- 868MHz SAW bandpass filter with 15MHz bandwidth
- Ultra-low noise figure of 0.75dB
- Dual power options: USB-C or 5V bias-tee input
- High-quality SMA female connectors for reliable connections
- Visual power indication via RED LED
- Compact and robust design for laboratory or field use

How to UseInstallation is straightforward - simply connect the preamp between your antenna and SDR receiver using the SMA connectors. Power can be supplied either through the [USB-C port](https://core-electronics.com.au/usb-c-cable) or via bias-tee from compatible devices like the [Airspy HackRF One](https://core-electronics.com.au/hackrf-one.html). For optimal performance, pair with an appropriate 868MHz antenna such as the [SparkFun DiPole Antenna - SMA, 2dBi (868MHz)](https://core-electronics.com.au/sparkfun-dipole-antenna-sma-2dbi-868mhz.html).

### Important Usage Notes

- This unit is designed for reception only - do not transmit through it
- Maximum bias-tee input voltage is 5V
- Not suitable for Helium cryptomining applications due to no TX bypass
