RF Filters are critical devices that ensure signal integrity of transmitters and receivers.  Whether you need to comply with governmental emission regulations, improve your system’s signal to noise ratio, or manage frequency coexistence, Richardson RFPD supports a wide range of filter technologies and topologies to meet your requirements.  SAW, BAW, Ceramic Dielectric, Multilayer Organic, Stripline, and Cavity filters are within our portfolio.  Standard, orderable options are viewable on our website, but customization is available upon request.  Please contact us for a custom filter.

CTS’s low-pass filters can be used with other CTS products, as a stand-alone solution, or as a complement to other filter technologies. All such bandpass filters or duplexers are resonant filters that have reentrant modes that do not provide harmonic suppression. Moreover, the 3GPP industry standards require suppression through 5th-order harmonics.

ClearPlex® is a type of RF filter based on CTS’ proprietary ceramic waveguide technology that supports even better performance than traditional ceramic dielectric filters:

  • Nearly twice the Q-Factor
  • Even higher power handling
  • Excellent passive intermodulation (PIM) performance

CTS ceramic frequency-signal Bandpass Filter (BPFs) are especially well-suited for use in indoor and outdoor TDD Small Cells.

  • Center Frequency: 6-12 GHz
  • Bandwidth: 0.15-2.0 GHz
  • IL: 1.2-2.5 dB
  • RL: ≥ 10 dB
  • Stopbands: ≥ 30 dB
