Typical Application

---

The band-reject filter SBR1741-x consists of high-Q resonators association intended to various VHF DMR and ground-to-air radio system. Cavity resonators are inherent temperature compensation providing a very low frequency drift with temperature variation. Optional 19 inches rack-mounted is available.
Band-reject filter is used to improve the isolation between transmitters and receivers when they operate in duplex mode with little frequency separation. The filter is also used to reject undesired signals and to avoid intermodulation effects.
