Generals. The TMR 2/70 is a 2 GHz microwave link receiver that can carry simultaneously 1 video and up to 4 high-quality 15 kHz analog audio programs. The RF input frequency is 1.3 - 2.7 GHz. The IF output is 70 MHz. The audio channels are fully compatible with the ITEL digital audio codecs TD/16 and RD/16 (2-channels).
Features. Some TMR 2/70 microwave characteristics are:
-the
A/V intermodulation almost canceled;
-the
capacity to accept simultaneously 1 video, up to 8 digital audio programs,
and up to 4 x 4800 bps data channels;
-
the easy RF frequency setting with a 125 kHz steps digital PLL. No tuning
is required within 100 MHz range.
Antenna connection. ITEL parabolic antennas enable the direct connection to the microwave feeder without wave-guide losses.
Metering. A front panel digital multimeter and alarms permit
to check audio and video levels, RF received signal level, PLL lock
and squelch status. The equipment meets or exceeds the international
standards for safety and electrical specifications.
