Abstract

In this paper, a W-band transmitter with 33dBm output power is designed. The transmitter consists of GaAs-based MMIC, GaN-based MMIC and the power control module. Each module is internally composed of MMIC chip, W-band micro-strip probe, wave-guide cavity structure and power bias conversion circuit. the whole modules cascaded is calculated first; then the micro-strip probe and MMIC module are modeled and simulated; Finally, the test results showing that the actual insertion loss of the micro-strip probe with wave-guide conversion structure is about 0.7dB, and the measured results are consistent with the simulation, indicating a good design. The saturation output power of the transmitter is above 33dBm in 90-96GHz band.
