TMLP5/2G
Portable Microwave Links
 
 

 

Generals. The TMLP5/2G microwave link is designed to satisfy the most TV demanding requirements at an effective cost. The TV link is composed by the transmitter (TMT), the receiver (TMR) and 2 directional antennas (LOG/2GR). The output power of the TMT transmitter is 5 W.

Performances. With the TMLP5/2G TV link, the following performances are guaranteed:
- A/V intermodulation is almost canceled;
- RF frequency channels are easy to change with a 125 kHz steps digital PLL. No tuning is required within 100 MHz range;
- All circuits are fitted into boxes suitable to be mounted at the rear of parabolic antennas with direct connection to the microwave feeder.

Digital audio compatibility. The audio channels are fully compatible with the ITEL digital audio coders TD/16 and decoders RD/16.

Instant installation. ITEL parabolic antennas enable the direct connection to the microwave feeder without wave-guide losses.

Full monitoring. A front panel digital multimeter and alarms permit to check audio and video levels, RF signal level, PLL lock and squelch status.

Meets or exceeds all the international standards for safety and electrical specifications.
