| Zusammenfassung: | FIELD: radio engineering. ^ SUBSTANCE: device has transmitter radio signal exciter 1, power amplifier 2, low frequencies filter 3, in track of which first high-speed commutator is used on p-i-n diodes 12; control device 17, output of which is connected to control inputs of high-speed commutators on p-i-n diodes. Low-frequencies filter is made in form of serially connected resonance contours, and during operation of receiver control device provides for disabling of exciter and locking of power amplifier, and first high-speed commutator on p-i-n diodes connects one end of inductiveness coil to body, second end of which is low-frequency filter output. ^ EFFECT: higher speed of operation, higher efficiency. ^ 1 dwg |
