Abstract
A 14 GHZ receiver designed for OTS is shown. After a quick survey of critical specifications, pointing out which ones have got an impact on the design choice and reasons of choices are explained. A short theoretical point is discussed: how overall performances of a receiver can be deduced from performances of each part. Then technical and technological aspects of the mixer. the multiplexer. the diode and the 10w noise amplifier are discussed. Results are given showing noise figure down to 6 dB over 350 MHz bandwidth. interface problems between mixer and amplifier are briefly explained. In conclusion margin between the best laboratary measurement and acceptable specification is detailed.
