Design approach for I-Q Modulators using Millimeter-Wave Monolithic Doubly Balanced V-Band Star Mixers

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 bandw...

SiGe HBT wideband amplifier for millimeter wave applications

A wideband amplifier up to 50 GHz has been implemented in a 0.25 μm, 200 GHz f t SiGe BiCMOS technology. Die size was 0.7×0.73 mm. The two-stage design achieves more than 11 dB gain over the whole 20 to 50 GHz band. Gain maximum was 14.2 dB at 47.5 GHz. Noise figure was lower than 9 dB up to 34 GHz and a current of 30 mA was drawn from a 4 V supply. To the author’s best knowledge this is the hi...

Millimeter-Wave GaN HEMT for Power Amplifier Applications

Gallium nitride high electron mobility transistors (GaN HEMTs) were developed for millimeter-wave high power amplifier applications. The device with a gate length of 80 nm and an InAlN barrier layer exhibited high drain current of more than 1.2 A/mm and high breakdown voltage of 73V. A cut-off frequency fT of 113GHz and maximum oscillation frequency fmax of 230GHz were achieved. The output powe...

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...
