A MULTIRANGE UNIFIED DIGITAL MICROWAVE RELAY
SYSTEM
A digital relay system is
intended for establishing relay telephone lines and data
transmission using digital methods as well as multiplexers
of pulse code modulators (IKM-30 and IKM-120) over the
ranges of 10,7 and 14,4 ÷ 15,35 GHz.
The radio equipment ensures constructing duplex relay
lines intended for digital data transmission at a speed
up to 8,448 Mb/s.

TELEVISION
TRANSMITTER-RECEIVER SYSTEM "MEDEYA"
This
is a miniature system of transmitting video information
to a remote or close television monitor by the radio-channel
with an amplitude modulation of A3F over the frequency
band of 1300-1500 MHz using the tuned directional antennas
(flagpole antenna, dipole antenna). It is intended for
remote control over various objects and actuating mechanisms
in real time. Amplitude
modulation is performed directly on the carrier frequency
(two side bands), the spectrum width for a television
signal with 625 scanning lines is 13 MHz. APPLICATION
AREAS: •
Small arms for night fighting; •
Intrusion alarm system; •
Industrial equipment; •
Means of transport; •
Intellectual toys.
The
system consists of GaAs integrated circuits: •
An active balance modulator with a bandwidth on inputs
of a signal and oscillator - 0...2000 MHz; •
A linear balanced power amplifier in a frequency band
0…2000 MHz (with a gain ripple of 3 dB); •
An up-down converter with a bandwidth in the range of
0…2000 MHz - at the output of 100 Om.
