Abstract
An ultra compact, varactor tuned phase shifter for adaptive antenna combining is presented. The passive circuit has been optimized for 802.11a and HIPERLAN applications. Only one control voltage is required to reach a phase control range of 360' from 5GHz up to 6GHz. At 5.5GHz, a maximum loss of 7.6 dB and an output compression point of higher than 12dBm were measured. The GaAs MMIC requires an effective circuit area of only 0.8 mm2.
