چکیده

In this paper, a doubly balanced V-band star mixer has been designed following the design method developed for I-Q modulators applications. The mixer has been designed using a commercial GaAs pseudomorphic HEMT process library. The mixer exhibits RF bandwidth over 45-65 GHz with local oscillator isolation better than 30 dB, and achieved a typical conversion loss of 9 dB. The IF modulation bandwidth is over 10 GHz, making the mixer suitable for high speed data transmission.

Integrated Antenna With Direct Conversion Circuitry for Broad-Band Millimeter-Wave Communications

A compact integrated antenna with direct quadrature conversion circuitry for broad-band millimeter-wave communications is proposed. The conversion circuits include two even-harmonic mixers based on antiparallel diode pairs (APDPs). The equivalent circuit of the APDP derived here provides good agreement with the measured data from 17 to 23 GHz. Overall phase and amplitude imbalance between the i...
