A harmonic mixer for the 20-40-GHz range
Abstract
It is pointed out that many of the emerging requirements for millimeter-wave applications involve an augmentation of existing systems. In this connection, it is frequently crucial that components meet requirements related to low cost and small size. A wide-band harmonic mixer for meeting the considered requirements was designed and fabricated. In the design, use has been made of hybrid, lumped element and microstrip techniques to obtain size and cost advantages while providing comparable performance. The mixer employs a beam-lead GaAs Schottky-barrier diode. The manufacturer's data sheet gives a capacitance of 0.1 pF and a cutoff frequency of 300 GHz at 0 V. This leads to a series resistance of about 5 Ohms.
