Abstract

This report describes construction and performance of the millimeter-wave solid state regenerative repeaters which were designed and built for use in the field trial circuit of the "W-40G" guided millimeter-wave transmission system presently under development at Electrical Communication Laboratories, NTT, Japan. The repeater consists of five kinds of panels; a transmitter-receiver panel, a delay equalizer panel, a MODEM panel and two auxiliary panels. The transmitter-receiver panel, which is described in some detail in this report, has a front end noise figure of about 11 dB, an output power of 9 dBm and a transmission bandwidth of about 0.8 GHz, in the 80 GHz region. A good regenerative performance of the repeaters in the 50, 60 and 80 GHz band was confirmed in the 22.7 km long field trial circuit.
