  • Our eXpandable transmit combiners can combine from 1 to 21 channels. The XTC series of filters incorporates expandability, close frequency spacing and some of the lowest insertion losses in the industry.

    Using a 6.625” cavity, the XTC can easily support 250 kHz Tx-Tx spacing.

    Each cavity is constructed using a gold alodine finish, silver-plated loops, silver-plated connectors and internal tuning plunger.

    Additionally, cavities are temperature compensated for operation between -40ºC to +60ºC. Every cavity is equipped with both coarse and fine tuning rods for quick and easy field or lab re-tuning.
