TV hardware specialists Electrocraft have recently announced the release of a new UHF/VHF programmable channel pass filter system that features double SAW filtering to produce outstanding adjacent channel processing. Made in Spain by ALCAD, the system comprises individual channel pass filters, a mounting rack and launch amplifier.

The rack is capable of accepting 10 active filter modules that can be individually programmed. In this way a simple and cost effective head-end can be assembeldbled with outstanding performance. The main advantage of the use of double SAW filters is the amazing 70dB selectivity figure, which means that unwanted adjacent channels can be eliminated.

Even without the optional ALCAD launch amplifier, the maximum output level is a very respectable 78dB. This could be fed into an existing launch amplifier. Frequency range of the system is 174-238MHz and 470-862MHz and the system does require an input level of 50-70dBuV for digital signals and 60-80dBuV for analogue signals. At an average cost of $200 per channel, this system will suit many installations where full COFDM processing is not required. Contact  Electrocraft for full details. (02 9438 3266)
