Linwave engineers have produced several point to point/multipoint radio transceiver designs at 23/24/26/28/38GHz for wireless local loop and cellular backhaul applications. These are full transceiver modules, typically incorporating a MMIC LNA in the receiver front end and a balanced MMIC power amplifier in the transmitter. The millimetre wave designs usually incorporate internal local oscillator multiplication and buffering, and can be provided with an integral 2 port diplexer if required.
