XTC – XPANDABLE TRANSMIT COMBINER SERIES – 7-INCH CAVITY

 

The XTC is the newest evolution of our X-Pass technology. Our Xpandable Transmit Combiners can combine 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 inch cavity, the XTC can easily support 125 kHz Tx-Tx spacing or 75 kHz spacing while using 10 inch cavities. Each cavity is constructed using a gold alodine finish, silver-plated loops, silver-plated con- nectors and internal tuning plunger. Additionally, cavities are temperature compen- sated 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.
