Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, has released a low cost Diplexer, to separate or combine all the cellular wireless frequency bands from the WiMAX and WiFi bands above 3 GHz.
With the 'Tuned-by-Design' approach, unit price is kept low by elimination of the high cost of manual tuning used in conventional designs, while still maintaining very low loss and >50 dB isolation between primary bands.
Such performance is usually more than sufficient for many applications, such as sharing a common antenna or in a distributed antenna system.
The low band extends from 80 to 2700 MHz, incorporating Tetra to the proposed new LTE bands up to 2700 MHz. The high band, 3,300 to 5,850 MHz, includes all proposed WiMAX bands and the WiFi to 802.11(a). Passive InterModulation, PIM, is specified at <-150 dBc, and guarantees down to -160 dBc are available with an additional testing charge.
The Diplexer is available from RF Parts Australia.
