RF filters for selective transmit and receive paths.
Our RF filters help suppress unwanted frequencies and select the wanted band. Band-pass, low-pass and band-stop filters are selected according to the required passbands and stopbands.
01 / SELECTION & INTEGRATION
Filter function and frequency plan
The filter must suit the intended signal path. Assess the passband, stopband frequencies and required attenuation together with the levels of wanted and interfering signals.
- Band-pass filters for a defined operating range.
- Low-pass filters to suppress higher frequencies.
- Band-stop filters to attenuate selected unwanted frequency ranges.
02 / SELECTION & INTEGRATION
Comparing performance parameters
Frequency alone does not fully describe a filter. Its transmission response and matching to the intended measurement or device interface are decisive.
- Insertion loss, stopband attenuation and roll-off.
- S11/S22, return loss and port impedance.
- Dimensions, connector type and approved operating conditions specified in the data sheet.
03 / SELECTION & INTEGRATION
Adaptation to your frontend
If an existing version does not suit the frequency plan, we assess customisation or a new design. We consider the filter and LNA together with the receiver path loss budget.
- Adjustment of centre frequency, bandwidth and stopbands.
- Integration as a PCB structure or connected assembly.
- Prototypes, measurement data and volume production as agreed.
