TC Tunable Bypass
The TC Series Filters yield a butterworth (maximally flat) response and are available with 2 thru 8 cavities. Tuning is accomplished by means of a single knob which is coupled to a precision gear train. All conducting surfaces are silver plated to minimize insertion loss in the passband. Filters in this series are available in tuning ranges from 395-8400 MHz. Outline drawings available upon request.
