Abstract :
The full integration of the 5-GHz front-end of MLS (microwave landing system) equipment shows the maturity of the GaAs application specific integrated circuit (ASIC) design. The architecture uses five GaAs chips on a 2-in/sup 2/ hybrid. All the different functions, such as amplifiers, switches, oscillators, and mixers, as well as digital functions needed for fractional divider frequency synthesis. have been integrated. All the designed ASICs fully comply with specifications and allow the equipment to run in a military environment. The results in terms of spectral purity are very satisfactory.<>
