A broad-band second-harmonic mixer covering 76-106 GHz
Abstract
A broad-band second-harmonic millimeter-wave mixer has been constructed. The circuit consists of a single unencapsulated Schottky-barrier diode and an embedding network which includes a wave absorber in the IF output terminal. The conversion loss of the mixer is 14.6 + or - 0.9 dB over a frequency range of 76-106 GHz. The mixer is pumped by a local oscillator that is tuned over the range of 37.15-52.15 GHz. The IF is kept constant at 1.7 GHz. The new mixer looks attractive for use in broad-band millimeter-wave measuring equipment, such as spectrum analyzers.
