Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a 120-GHz-band binary phase shift keying (BPSK) modulator and demodulator fabricated on microwave monolithic integrated circuits (MMICs) for a 10-Gbit/s wireless link. The direct-conversion modulator consists of a 180 hybrid coupler, gain-control amplifiers and Wilkinson combiner. The delay demodulator has a 100-ps delay line made of coplanar waveguides and a voltage-controlled phase shifter. The modulator MMIC exhibits a static vector error magnitude of 5%. The modulator and demodulator MMIC were mounted in WR-8 waveguide modules to evaluate the characteristics of 10-Gbit/s transmission. A bit error rate (BER) for 10-Gbit/s pseudorandom binary sequence (PRBS) 27-1 data was smaller than 1E-12.
