Dc Offset Suppression in Double Balance Direct Conversion Receivers
The double balance mixer scheme in-phase signal input and double-quadrature Local Oscillator (LO) is suggested for application on IQ direct conversion receivers. The influence of the gain and phase mismatches of splitters is investigated. It is shown that a similar scheme using square-law detectors is promising on optical applications. Introduction The increasing interest in direct conversion r...

متن کاملRenaissance of HF DC (Direct Conversion) receivers
First receiver I was ever built for HF was tube receiver without RF amplification called OV2 .It was working good and enable me to listen short waves and HAM bands. After that I build super heterodyne receivers but when I built DC transceiver by W7EL at the beginning of 80’s ZL2BKW version I was surprised how good DC receiver can be. With simple dipole antenna for 7MHz I worked 102 DXCC in 1985...
متن کاملFrequency Offset Estimation Scheme in the Presence of Time-Varying DC Offset for OFDM Direct Conversion Receivers
This paper presents a frequency offset estimation scheme for Orthogonal Frequency Division Multiplex (OFDM) direct conversion receivers. The key idea is to use a differential filter for reduction of DC offset. Frequency offset is estimated in the presence of time-varying DC offset. In order to overcome the varying DC levels under automatic gain control (AGC) circuits, a threshold level is set f...
متن کاملDC Offsets in Direct-Conversion Receivers: Characterization and Implications
Direct-conversion receivers (DCRs), also known as zero-IF or homodyne receivers, have received significant attention over the last decade and have become a popular alternative to the classical heterodyne architecture (which has dominated receiver topologies for more than 70 years) in the development of RF integrated circuits (ICs) for wireless applications. Rather than downconverting to a finit...
