DCPL-WB-00D3

The DCPL-WB-00D3 is a wide-band, dual-path directional coupler designed to measure cell phone transmission output power in GSM/WCDMA applications. This dual path CPL has been customized for wide-band operating frequencies (EGSM and CELL, PCS, DCS, WCDMA band I) with less than 0.2 dB insertion losses in the transmission bandwidth (824 MHz - 1980 MHz).This device is built with two different RF couplers (one dedicated to LB, the other dedicated to HB) sharing the same coupled and isolated ports.The DCPL-WB-00-D3 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.
