An RF (Radio Frequency) filter is a passive component used in RF and microwave systems to block unwanted frequencies and allow desired frequency ranges to pass. These filters are essential in managing signal integrity by preventing interference, reducing noise, and improving the performance of receivers and transmitters.
Types Of RF Filters
Low Pass Filters – Allow frequencies below a certain threshold to pass while blocking higher frequencies.
High Pass Filters – Pass frequencies above a set point and reject those below it.
Band Pass Filters – Permit only a specific range of frequencies to pass through.
Band Stop (Notch) Filters – Attenuate signals within a narrow frequency range while allowing others through.
Key Features of Our RF Filters
We offer both standard and custom RF filters with the following features:
- Wide Frequency Range – Covering MHz to multi-GHz frequencies
- High Selectivity – Sharp roll-off and minimal insertion loss
- Compact & Robust Designs – Built for harsh and space-constrained environments
- Low VSWR – For improved signal integrity
- Surface Mount & Connectorized Options – Flexible integration into any system
- Shielded Enclosures – To minimize EMI and crosstalk
