In this paper, a terahertz wideband sub-harmonic mixer based on the Schottky anti-parallel diodes pair and MASTER technology is presented. The mixer circuit is fabricated on a 0.05mm quartz substrate including Schottky anti-parallel diodes pair, RF/LO transition, IF matching networks and filtering circuits. The diode circuit is fabricated on a quartz substrate directly by MASTER technology. The research...
Direct conversion architectures have the advantage of no image frequencies, fewer components and lower cost. However local oscillator (LO) leakage reduces receive sensitivity, causes LO pulling, and is a challenging problem for direct conversion transceiver design. A mixer using the 2nd-order harmonic of LO is thus desired to address this issue. The sub-harmonic mixer, proposed in this paper, is based...
A multi standard direct conversion receiver for digital video broadcast application is presented. This receiver supports MediaFLOtrade, DVB-H and ISDB-T standards. Broadband multi-standard operation is achieved with a reconfigurable LNA, broadband mixer, programmable bandwidth baseband filter, wide tuning range LC VCO with a fully integrated fractional-N synthesizer. A high linearity signal path enables...
