Pin configuration (bump view) Lead-free CSP package Small footprint: 1670 x 1440 m A3 A2 A1 Very low profile (< 650 m thickness) LB Path Benefits B3 B1 High RF performance HB Path RF module size reduction C3 C2 C1 Complies with the following standards: IEC 61000-4-2 level 4: 15 kV (air discharge) Description 8 kV (contact discharge) The DCPL-WB-00D3 is a wide-band, dual-path Applications directional coupler designed to measure cell phone transmission output power in Multi-band equipment such as: GSM/WCDMA applications. This dual path CPL Power amplifier module has been customized for wide-band operating frequencies (EGSM and CELL, PCS, DCS, Front end module WCDMA band I) with less than 0.2 dB insertion GSM/WCDMA mobile phone 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. April 2011 Doc ID 17967 Rev 1 1/11 www.st.com 11Characteristics DCPL-WB-00D3 1 Characteristics Table 1.
