Description
The CPL-WB-01D3 is a wide-band directional
coupler designed to measure RF antenna output
power in GSM / WCDMA / TD-SCDMA
applications. 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.
