Frequently asked questions

What is the passband and insertion loss of the AW-BPF-3700-4100-S?
The AW-BPF-3700-4100-S is a cavity band-pass filter with a 3700–4100 MHz passband and typically less than 0.5 dB insertion loss in-band, so it protects your link budget while rejecting out-of-band energy by more than 50 dB.
How much power can it handle, and what connector does it use?
It handles more than 50 W average power, is 50 ohm, and ships with SMA female connectors. N-type or 4.3-10 connectors are available on request.
Can you make a custom passband, bandwidth or connector?
Yes. We build custom center frequencies, bandwidths and connector options to your frequency plan — send us your required passband and rejection points and we will quote a custom unit.
Is it suitable for outdoor, mast-mounted use?
Yes. The housing is IP67-sealed aluminum rated for -40 to +85 C, designed for outdoor PtP/PtMP, WISP and UAV installations.
Do you provide measured test data?
Every unit is swept on a vector network analyzer and labeled with a traceable serial number before shipment. The measured S21/S11 response is shown on this page, and a test report is available on request.
