MICROWAVE RADIO LINE Russian patent published in 1997 - IPC

FIELD: radio communication, in particular, connection between computer systems and for computer- aided manufacturing. SUBSTANCE: device has spaced receivers and transmitters. Said receivers and transmitters are designed as radio relay transmitters each of which has directional antenna, which is connected to reflecting microwave amplifier made in Gunn-effect diode, which anode circuit is connected to gate modulator and low- pass filter of signal processing unit in parallel. Low-pass filter bandwidth Δf, signal delay τ_d and self-exciting oscillations setting time t_set in radio line conform to condition , where t_set = (10÷20)2τ_d.. EFFECT: increased functional capabilities. 4 dwg
