BRF 2/3 BNC

Band Reject Filters BRF 2/3.

Band-Reject (Notch) Filters for the 160 MHz.

The BRF 2/3 is a 3-cavity notchfilter using helical resonators.

This filter rejects a narrow band of frequencies in the 2 m band and passes all others in the range 0 - 430 MHz. The filter can be applied both in connection with transmitters and receivers to attenuate interfering signals causing cross modulation effects. The filter can be employed as a single component or it can function as an integrated part of a complete multicoupling system.

The BRF 2/3 can be tuned within the complete 144 - 175 MHz band. Careful design and choice of materials ensure reliable operation over a wide temperature range.

The housing is made of extruded aluminium, the chassis of passivated steel, and teflon insulation has been applied in the coaxial cables and in the connectors.

The filter is black-vinyl coated to prevent corrosion.
