Delta Meccanica: Compact DVB-T filter

A DVB-T filter with 1 kW RMS of power in the VHF band has been released.

Delta Meccanica’s filter features four poles, which helps to keep the insertion loss lower than 0.4 dB according to the company, with a return loss better than 24 dB.

The filter is compact, with a combline configuration, allowing it to be housed in a 19-inch rack, with an height of just 2RU.

Delta Meccanica said that it also, after careful examination of thermal behaviour of the filter, optimised the temperature compensation to improve the filter’s stability and performance.
