Development of an RF Direct-conversion Transmitter for Wireless Applications
Advisor: Prof. Anh-Vu Pham
The heart of every wireless communication
device consists of a transmitter and a receiver to transmit and
receive information. An RF transmitter performs mixing or upconversion
of baseband signals (voice or data) to a desired RF frequency
band, power amplifying, then transmitting the information. Conventionally,
The architecture of a RF direct-conversion transmitter will be investigated for upconverting baseband signals to an RF frequency band. Although this technique is attractive to reduce the component count, it faces challenges such as shielding the power amplifier and a VCO and meeting spectral mask requirements. During the summer research program, students will be involved with the design and development of a direct-conversion transmitter using a commercial software package, Advanced Design System (ADS). Off-the-shelf components will be provided to implement transmitter prototypes that will meet communication standard specifications such as Bluetooth. Students will have the opportunities to test and analyze these transmitters using a Signal Vector Analyzer and a Digital Signal Generator.
