Q-band coplanar waveguide amplifier

Q-band monolithic amplifiers using CPW (coplanar waveguides), GCPW (ground coplanar waveguides) and MS (microstrip) structures were designed and RF-evaluated. At 44 GHz, the CPW amplifier exhibited a gain of 7.5 dB, while the GCPW amplifier exhibited a gain of 7.0 dB. These results compare very favo...

Summary:Q-band monolithic amplifiers using CPW (coplanar waveguides), GCPW (ground coplanar waveguides) and MS (microstrip) structures were designed and RF-evaluated. At 44 GHz, the CPW amplifier exhibited a gain of 7.5 dB, while the GCPW amplifier exhibited a gain of 7.0 dB. These results compare very favourable with the MS amplifier, which has a gain of about 7.5 dB. It is concluded that these results are encouraging and show the great promise of future millimeter-wave monolithic microwave integrated circuit implementation using this structure.< >
