GaAs monolithic 1.5-2.5 GHz image rejection receiver

The design and performance of a microwave receiver design using GaAs monolithic technology are described. The receiver has been designed for use in digital radio links at 1.5-2.5 GHz. Its main features are its low noise figure and image frequency rejection. The receiver consists of two GaAs chips; a low-noise amplifier (LNA) and an image rejection mixer. The LNA achieves 19-dB gain with an associated noise figure of 1.7 dB. The image rejection mixer allows 20 dB of image suppression. The whole receiver exhibited a total gain greater than 31 dB and an associated noise figure lower than 2.5 dB over a 1-GHz bandwidth.<<ETX>>
