This paper describes a single-chip W-band frequency multiplier MMIC in a waveguide package. The multiplication factor by 12 has been obtained with a doubler, tripler and doubler chain. The MMIC has been realized in a 100 nm metamorphic HEMT technology. It has been packaged in a split-block module using a high precision 50 μm thick quartz transition for the W-band output and a low cost ceramic transition on the input. A power supply board, embedded in the module, provides six different voltages to the MMIC. The packaged frequency multiplier achieves an output power of -0.8 dBm, a conversion gain of 0.2 dB and a 3-dB bandwidth of 16 GHz from 86 to 102 GHz with a suppression of the unwanted harmonics of more than 25.5 dBc. The phase-noise of the output signal is not affected by the multiplier circuit.
