Course Information


Wireless application circuit design for gain and filter control at radio frequencies to interface the baseband processing systems and the antennas of communiation systems. 4605: Design of radio transmitter and receiver circuits using scattering-parameter methods. Circuits include oscillators, radio frequency amplifiers and matching networks, mixers and detectors. 4606: Design of amplitude, frequency, and pulse-modulated communication systems, including modulators, detectors, and the effects of noise. Design basics and guidelines for phaselocked loops and several power amplifier configurations.
