The DCPL-WB-02D3 is a wide-band, dual-path
directional coupler designed to measure
transmission output power in WLAN applications.
This dual path CPL has been customized for
wide-band operating frequencies (2G/5G WLAN)
with low insertion losses in the transmission
bandwidth (2400 MHz - 5850 MHz).
This device is built with two different RF couplers
(one dedicated to LB, the other dedicated to HB)
sharing the same coupled ports. Isolated port is
loaded with an integrated 50 Ω resistor.
The DCPL-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.
