A Single Sideband RF-Modulator for Digital-IF Transmitter

The limitation of the single-sideband rejection ratio (SSRR) performance of transmitters based on I/Q mismatching due to high frequency signals has been investigated. The proposed single-sideband radio frequency-modulator (SSM) is capable of generating a single sideband frequency without implementin...

Zusammenfassung:The limitation of the single-sideband rejection ratio (SSRR) performance of transmitters based on I/Q mismatching due to high frequency signals has been investigated. The proposed single-sideband radio frequency-modulator (SSM) is capable of generating a single sideband frequency without implementing a quadrature local oscillator which displaces a phase of a local oscillating signal by 90deg at a high frequency. This technique is promising for radio transmission with a SSRR of more than 60 dBc. Also, the architecture of digital-intermediate frequency transmitter using the proposed SSM can be applied for a future software-defined radio solution supporting multiband and multimode wireless communications.
