Bandpass filters
Single-band cavities from 703 MHz to 3.8 GHz, plus a low-loss 2.4 GHz unit. Rejection tables are on each datasheet.
OpenCavity filters · Shenzhen · Thirty years
Kangxuntong builds cavity bandpass filters, diplexers and multi-band combiners in Shenzhen. Documented passbands run from 135 MHz to 6 GHz. The indoor cellular line is concentrated from 700 MHz upward. Each shipment includes a network-analyzer test report.

The catalog follows the specifications already written for current products.
Single-band cavities from 703 MHz to 3.8 GHz, plus a low-loss 2.4 GHz unit. Rejection tables are on each datasheet.
OpenTwo-port and four-port cavity combiners for 700 MHz through n78 and 5 GHz Wi-Fi.
Open5150–5370 MHz and 5450–5850 MHz in one housing, 80 dB between passbands.
OpenIndoor DAS, repeater remotes, and band cleanup around LTE and 5 GHz Wi-Fi.
Insertion loss, ripple, VSWR and rejection on the datasheet are the limits from the factory specification for that model. Return loss is the calculated equivalent of VSWR ≤ 1.3.
Tuning is done on a vector network analyzer. The report covers the electrical rows. Low PIM at ≤ −150 dBc @ 2×43 dBm is an order option, measured when it is ordered.
Outline drawings from the specification are printed on the datasheet, with mounting holes where the drawing states them.
Send the band plan, rejection, power, connector and envelope. The quotation states the lead time. We do not print a universal lead time here.
