Abstract
A broadband multifunction MMIC, achieving combined amplification and phase shift, has been developed on 2 (3.2 x 4) mm² chips using the UMS PH25 process. The frequency range is as large as characterised by a ratio of Fmax/Fmin = 6. The 5 bit phase shifter section is based on switched "all-pass" cells. The amplification function is realised through active switches consuming less than a total of 40 mA under 3V and providing an overall gain of about +6 dB.
