ANALOG MICROWAVE LINK

The high stability synthesized oscillators permit easy and rapid frequency changes. On both TX and RX there is a double IF output 70MHz@0dBm standard, for any eventual IF linking with other radios. The systems are provided with a multifunctional display which allows to check entire operating parameter, alarm led for Audio and Video overmod and a remote control interface through RS-232 port. The ELK series is available in different frequency ranges from 1.5 to 14.5GHz with different output powers both in the internal versions and with external RF heads. In the latter case modulator / demodulator are fixed in 3HE cabinet while up/down converter are fitted into waterproof tin cases suitable to be mounted on the rear of parabolic antennas. The external head is connected to the internal console by a single coaxial cable which passes both the IF signal and the power supply.

ELETEC analog microwave links of ELK series have been engineered to deliver one video and four audio channels (two standard) broadcast – quality. The modular mechanical design and the solid state philosophy employed for their realization permit the housing of the complete system, for the three typical configurations (TX, RX and RP), in a 3HE 19” rack cabinet. The superior performances of these products are mainly due to the measured signal to noise ratio (SNR), the group delay and pre-emphasis and de-emphasis circuits (manually disabled) included in the modulator and demodulator section respectively.

For particular difficult connections, a series of external solid-state amplifiers, including those at high-power, is also available.
