AbstractA 60‐GHz highly integrated small mobile terminal (MT) with integrated IF modem for a high‐data‐rate millimeter‐wave radio‐on‐fiber communication system is proposed and inspected by the BER and PER experiment between the access point and mobile terminal. This terminal integrates a 60‐GHz transmitter, receiver, and IF modem in one module. To minimize the volume of the mobile terminal, a microstrip line to rectangular waveguide transition, surface‐mountable three‐pole bandpass filter, successive detection‐log video amplifier (SDLVA), and DPSK demodulator are used. As the performance of this mobile terminal is confirmed by the experiment results, it can access the high‐data‐rate (155.52 Mb/s) communication network in the picocell area. © 2005 Wiley Periodicals, Inc.
