QUARTZ FILTERS and HELICAL FILTERS

Monolithic quartz filters with sharp selectivity, small insertion loss and very high reliability. The range includes standard 10.70MHz, 21.40MHz, 45MHz fundamental and third overtone designs.

Also six and eight pole block filters with the option of matching transformers.

Quartz is the ideal resonator for selective narrow band filters providing a temperature stable, high Q resonant source together with a low mass and small size.

The TFC data includes a general range of filters available for applications with channel spacing requirements of between ±12.5kHz and ±50kHz complemented by single sideband filters and custom designs available for special applications.

Custom wound screened helical band pass filter coils are supplied from 45MHz ~ 2600MHz in 5mm and 7mm packages, double, triple or quadruple poles with 50 ohms and 75 ohms matching impedance.
