Description
The CPL-WB-02D3 is a wide-band directional
coupler designed to measure RF antenna output
power. This CPL has been customized for wide
band operating frequencies (2G/5G WLAN) with
low insertion losses in the transmit bandwidth
(2400 MHz to 5850 MHz).
The CPL-WB-02D3 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.
