The DCPL-WB-00D3 is a wide-band, dual-path directional coupler with ISO port 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).
The DCPL-WB-00D3 is a wide-band, dual-path directional coupler designed to measure cell phone transmission output power in GSM/WCDMA applications. It utilizes STMicroelectronics IPD technology on a non-conductive glass substrate and is delivered in a lead-free Flip Chip package with a small footprint of 1670 x 1440 um and a thickness of less than 650 um.
The device features two different RF couplers (one for Low Band and one for High Band) sharing the same coupled and isolated ports. It offers a wide operating frequency range from 824 MHz to 2170 MHz, with low insertion loss (< 0.2 dB) and high directivity (> 20 dB). The component complies with IEC 61000-4-2 level 4 standards for ESD ruggedness.
