Microwave Spectroscopy lab

Microwave spectroscopy laboratory is equipped with extensive inventory of RF and Microwave test and measurement equipment’s featuring Anechoic chamber (3.5m L x 1.7m W x 2.1m H) and R&S ZVA 50 vector network analyzer. The system is optimized for radiation characterization of microwave devices from 2~50GHz and transmission/reflection measurements (0.01~50GHz). Many small tools like power meter, DC-Blocks, wave guides, horn antennas (500MHz~50GHz) are also available for various application specific measurements.
