PGA103+Very low noise wideband amplifier, high IP3 data to 3 GHz

It is intended to direct connection with a coaxial relay like QRO Relay. To achieve the lowest possible losses without any additional coaxial cable. It will ensure the lowest possible NF (Noise Figure) for terrestrial and EME (Earth-Moon-Earth) communications.
PGA-103+ The low-noise amplifier is small enough not to interfere with the big central 7/16 DIN connector.
