This CPL has been customized for wide band operating frequencies (EGSM and CELL, PCS, DCS, TD-SCDMA, WCDMA Band I) with less than 0.2 dB insertion losses in the transmit bandwidth (824 MHz to 2170 MHz). The CPL-WB-01D3 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. February 2012 Doc ID 019036 Rev 3 1/10 www.st.com 10 Characteristics CPL-WB-01D3 1 Characteristics Table 1.
