Multiplexing and Demultiplexing Techniques with Gunn Devices in the Gigabit-Per-Second Range

In this paper a circuit is described which can process signals in the gigabit-per-second range for fast PCM applications. Such circuits will be interesting for future communication links, especially in connection with glass fibers. A monolithically integrated shift register with Gunn devices on GaAs is used. A circuit consisting of five stages is described and experimental results for bit rates near 2 Gbit/s are reported.
