This dual path CPL has been customized for wide-band operating frequencies (2G/5G WLAN) with low insertion losses in the transmission bandwidth (2400 MHz - 5850 MHz). This device is built with two different RF couplers (one dedicated to LB, the other dedicated to HB) sharing the same coupled ports. Isolated port is loaded with an integrated 50 resistor. The DCPL-WB-02D3 has been designed using STMicroelectronics IPD (integrated passive device) technology on non-conductive glass substrate to optimize RF performance. The device is delivered 100% tested in tape and reel.
