Tunable Bandpass Cavity Filters (UF9978)

November 06, 2018

Using over 50 years of high performance RF filter design and manufacturing experience, MtronPTI can provide field tunable bandpass cavity filters that could be used to tune desired signals while rejecting interfering signals in Air Navigation Systems Receivers.

Features: High Q, Low Insertion Loss, Better Selectivity, Power Handling, Excellent out of band performance

Applications: TACAN/DME Air Navigation Systems, Instrumentation


General & Electrical Requirements:

  • Passband Frequency Range: 1025 to 1150MHz min
