摘要

提出了一种用于自适应天线组合的超紧凑变容调谐移相器。无源电路已针对802.11a和HIPERLAN应用进行了优化。只需要一个控制电压就可以达到从5GHz到6GHz的360'相位控制范围。在5.5GHz时，测量到最大损耗为7.6 dB，输出压缩点高于12dBm。GaAs MMIC要求有效电路面积仅为0.8 mm2。

Varactor tuned phase snifter MMIC at C-band with 360/spl deg/ phase control for adaptive antenna combining

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.
