Wide band directional coupler with ISO port
  • active Active

The CPL-WB-00D3 is a wide band directional coupler designed to measure RF antenna output power in GSM / WCDMA / TD-SCDMA / LTE applications. This CPL has been customized for wide band operating frequencies (EGSM and CELL, PCS, DCS, TD-SCDMA, WCDMA Band I, B7, B17, LTE) with less than 0.2 dB insertion losses in the transmit bandwidth (704 MHz to 2570 MHz).

The CPL-WB-00D3 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.
