Abstract :
The author presents an improved amplifier design resulting from advances in substrate technology, semimonolithic processing techniques and component design. The result is a 26-40-GHz amplifier in balanced form offering 9.0-dB minimum gain, input and output VSWR (voltage standing-wave ratio) <2.0:1 and noise figure <6.0 dB. The circuit is fabricated using an advanced multilayer-thin film technology on a glass ceramic substrate material. Details and results for the quadrature coupler design, termination approach, and amplification technique are presented. Reduced fixed assembly costs, reduced parasitics, improved reliability and repeatable performance are the potential advantages of semimonolithic component design at millimeter-wave frequencies.<>
