Introduction
The facilities for microwave and millimeterwave circuit measurements are available in a temperature, moisture and dust controlled room. The probe stations in this laboratory are used for packaging substrate and PCB board testing. An Agilent 4 port network analyzer up to 20GHz and a 2-port VNA to 67 GHz can make scattering matrix measurement with probe stations. One Cascade Summit 9000 probe station is used for packaging substrate measurement. A two-sided probe station is designed for dual-side probing of PCB board and packaging substrate.

Introduction
The facilities for microwave and millimeter-wave circuit measurements are available in a clean room. The probe stations in this laboratory are used for the on-wafer chip testing. Agilent 50-GHz vector network analyzer which can be extended up to 170 GHz by the millimeter-wave modules and Anritsu 40 MHz to 65 GHz four-port vector analyzer are available for S-parameter measurements. Noise figure analyzer, spectrum analyzers, signal generators, load-pull systems, and oscilloscopes are also provided in this laboratory. In addition, we have Agilent precision semiconductor parameter analyzer and Auriga pulsed-IV system for the transistor dc characteristics testing. This laboratory provides the world-class measurement capability for the microwave and millimeter-wave circuits.

Introduction
The major research topics includes: the development of adaptive radio-frequency front-end circuits, including tuning filter and balun, and high-efficiency and high-linearity power amplifier, low-noise amplifier and single-pole-multi-throw transistor switch. We also establish a multiple-input-multiple-output transmitting/receiving system to validate the adaptive RF front-end circuits with various modulation schemes and data rates through wireless channels. Moreover, the essential components for high-efficiency and low-cost wireless charging system and near-field communication system are investigated.

Introduction
Main anechoic chamber for general purpose with operating frequency range 1-18 GHz, equipped with a vector analyzer Agilent 8722ES and a PC-based 3-axis motion controller that may position the antenna under test in an arbitrary direction for the 3D antenna patterns measurement. In addition, the position controller may also precisely control the source antenna for two orthogonal components enabling the system for the circular polarization measurement.

Introduction
Millimeter wave chamber for 40-65 GHz operation, equipped with an Agilent PNA E8361A (10MHz to 67GHz) and a 4-axis position controller. Besides the 3-axis control for 3D and CP measurements, the 4-th axis is for varying the distance between the antennas enpowering the system for the precise calibration on the antenna gain at millimeter wave frequencies where the errors due to the phase center uncertainty is significant.
