Research on “Spectrum monitoring system for the L Band” -Designed and assembled RF front-end and RF back-end of a superheterodyne receiver with high sensitivity using connectorized LNAs, amplifiers, filters, mixers, bias-Ts, synthesizers, and RF switches. -The receiver achieves a gain of 67 dB, a bandwidth of 10 MHz, and MDS of -120 dBm. -RF signal is sub-Nyquist sampled at 100 MSPS, and digitally down-converted to DC by a software-defined radio (USRP N200) before being streamed to a host computer via Gigabit Ethernet interface. -Designed and implemented transistor based digital control circuit boards and power supply circuit boards. -The digital control circuit boards are controlled by NI USB-6501 and LabVIEW to perform input switching (between the antenna and a matched load) for receiver calibration.
Scientific payloads for sounding rockets and satellites -Built scientific instruments including a Langmuir Probe system which could be mounted on sounding rockets for ionospheric plasma measurements. -Designed and simulated analog pre-amplifier and digital controller circuits using EDA tools. -Established PCB layouts using EDA tools. -Designed data acquisition boards with micro-controllers and A/D converters that communicate with computers via serial interfaces such as RS-232 and RS-422. -Designed graphical user interfaces for data acquisition with Visual Basic and LabVIEW. -Conducted tests on prototypes in a space plasma simulation vacuum chamber.
