Abstract
In this thesis, we present a new architecture of differential T/R switches for wireless local-area network (WLAN). If we use the balanced-type circuit, the number of the devices, such as a balun, can be reduced. The balanced circuit can also improve the poor ground and suppress the common-mode interference. In addiction, the proposed architecture consumes no DC power at the receiving mode, which is especially suitable for portable wireless applications.
The LTCC (low temperature co-fired ceramic) is chosen for its low loss and multi-layer structure, which will give better insertion loss and give more freedom in balanced-type device design. The design procedure and measurement results of two differential switches operating at 2.4GHz and 5.2GHz are presented in this thesis.
