A Times-4 Frequency Multiplier From K- To W-Band

In this paper, a times four K- to W-Band frequency multiplier involved in the generation of a Local Oscillator signal is presented. The chosen technology for this design is the D01MH, a metamorphic GaAs mHEMT with a 0.13 mu m channel length. The designed MMIC is expected to convert a 5 dBm, 23-24 GHz input signal into a 11 dBm, 92-96 GHz output signal. Simulations show an output power harmonic suppression over 50 dBc between the desired and unwanted ones. Input and Output matching respectively better than 13 and 16 dB is expected. The MMIC occupies an area of 3 x 2mm(2), and is currently being manufactured.
