Uputronics Filtered Preamp with Transmit Bypass Frequency:915 MHz LoRa/ISM 2x M2 screwThis 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
