Description
The DCPL-WB-00D3 is a wide-band, dual-path
directional coupler designed to measure cell
phone transmission output power in
GSM/WCDMA applications. This dual path 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 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.
