VHF-CMB-4-8″

RF/Microwave Wireless Communication Products

SekizA RF Solutions of Cavity Combiners consist of high Q value cavity filters and dual isolators of ours. They provide high isolation and protection for the receivers and the system. Can be tuned and used throughout the relevant frequency range.

If a number of receivers have to share the same antenna, this product can be used without loss of signal.
Suitable for 19″ rack cabinet mounting.
Has high blocking capability of intermodulation and interference in receiving and sending, respectively.
Cavity filters with a high ‘Q’ value are used.
Ensures high frequency stability over against temperature and power changes.
