A connectorized band-pass filter passes a defined frequency band and attenuates signals below and above that band. Compare the passband and insertion loss with the required rejection at each interfering frequency. Check the model’s connector interface, input-power limit, impedance and dimensions before ordering.
Use the model datasheets below to shortlist a connectorized RF bandpass filter. Send RFComp the model number or your filter requirements to request a quote.

Electrical, environmental and mechanical requirements
Provide the required frequency response, insertion loss or attenuation, impedance and RF power level. RFComp can review these requirements against available model specifications.
Specify operating and storage temperatures, vibration, sealing and other environmental requirements. Confirm each rating in the selected model’s datasheet; do not assume every model supports extreme conditions.
Provide connector type, package dimensions, mounting constraints and any space or weight limits. Confirm the mechanical drawing and interface requirements before ordering.
Start with the frequencies your system must pass and the unwanted signals it must attenuate. Center frequency identifies the nominal center of the frequency band; the passband specifies the range to evaluate. State the required lower and upper passband edges rather than relying on center frequency alone.
Compare RF bandpass filter specifications under the same stated operating conditions. Check the matching model datasheet, and ask RFComp to clarify blank cells, paired values or ambiguous frequency notation before selecting a part.
Bandpass filter insertion loss: Check the permitted signal loss across the required passband, including any stated variation with frequency or temperature.
Bandpass filter rejection: Specify the minimum attenuation needed at each interfering frequency or stopband. Read every rejection value with its stated test frequency; a single value does not establish rejection at every frequency outside the passband.
VSWR: Review input and output matching across the required band and confirm the system impedance.
Power and integration: Confirm the selected model’s input-power rating and operating conditions, along with connector type, package dimensions, mounting and temperature range. Do not treat an empty specification cell as zero or as an unlimited rating.
Insertion loss describes attenuation of the wanted signal in the passband. Rejection describes attenuation at specified unwanted frequencies. Check both across the frequencies that matter to your system.
Compare the model’s specified passband, stopband, power rating, impedance, connector interface and temperature limits with your requirements. A connectorized package alone does not establish frequency or environmental compatibility.
Send the passband and stopband limits, required rejection at specified frequencies, allowable insertion loss, power level, impedance, connector type, temperature range and quantity.
