Abstract :
We present the design approach, realization and test results of the Q-band precision subminiature coaxial adaptor. Coaxial adaptor based on transmission line theory using multi-step impedance and coaxial discontinuities to increase its cutoff frequency. The return-loss increments due to the hooked structure and multi air-holes are minimized to 2 dB and 1.5 dB, respectively. VSWR of < 1.2 is obtained from DC to 40 GHz, while guaranteeing the durability of the adaptor from room-temperature to 120degC.
