B RF module size reduction ISO GND CPLD Applications Quad band power amplifier module Description Quad band front end module GSM / WCDMA mobile phone The CPL-WB-00C2 is a wide band directional coupler designed to measure RF antenna output power in GSM / WCDMA applications. This 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 transmit bandwidth (824 MHz to 2170 MHz). The CPL-WB-00C2 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. January 2010 Doc ID 15088 Rev 3 1/8 www.st.com 8Characteristics CPL-WB-00C2 1 Characteristics Table 1.
