Concept diagram of frequency selection using combined high-pass and low-pass sectionsLong cyan dashes indicate the high-pass boundary; short gray dashes indicate the low-pass boundary. The blue outline illustrates the target passband defined by both. The lower high-pass boundary and upper low-pass boundary are labeled below. This explains functional relationships only, not internal circuitry or a measured response.High-Pass BoundaryLow-pass edgeTarget PassbandHigh-Pass Lower BoundaryLow-pass upper edgeFrequency

Typical Applications

For frequency selection and out-of-band interference rejection in RF signal chains for radar, communications, electronic countermeasures and instrumentation.

Selection Notes

  • The table shows a nominal range of 1–3GHz; the frequency range in the original datasheet electrical characteristics table is 1–2.85GHz.
  • Insertion loss is a typical value for selection and varies with operating frequency, bandwidth, and configuration. Refer to the relevant model datasheet and test results for specific conditions.
Public information is intended for preliminary product selection. Check specifications against the specific frequency, bandwidth, configuration, package, and interface conditions. For detailed technical documentation, specify the model and system requirements.
