Where these cavity filters are used.
The four-port combiners put 700/900, 1800, 2100 and 2300/2600, or Band 1 with 2.6 GHz and n78, onto one antenna feed. Port isolation on those sheets is 70 dB or 80 dB in the other passbands.
Single-band cavities at 50 W and 100 W sit on the BTS or repeater port: Band 28, Band 20, Band 8, Band 5, Band 3, Band 1 and Band 7, plus n78 at 50 W.
2400–2483 MHz and 2400–2485 MHz bandpass units, and the 5 GHz two-port combiners at 5150–5350 / 5725–5875 MHz, keep cellular energy out of the Wi-Fi path. The diplexer separates the two 5 GHz passbands by 80 dB.
The factory-file section includes a 400 MHz duplexer with full electrical limits, and the quotation roster lists a 135–210 / 400–500 MHz duplexer by passband only.
