Ultra Low Profile 0805
20dB Directional Coupler
Description
The DC4759J5020AHF is a low cost, low profile sub-miniature high
performance 20 dB directional coupler in an easy to use RoHS compliant, Halogen
Free surface mount package. It is designed for 4700 – 5900MHz applications
including: WiFi and P2P / P2MP applications. The DC4759J5020AHF is ideal for
power detection, signal injection and other applications where low insertion loss
signal monitoring is required. The DC4759J5020AHF is available on tape and reel
for pick and place high volume manufacturing. All of the Xinger components are
constructed from ceramic filled PTFE composites which possess excellent electrical
and mechanical stability. All parts have been subjected to rigorous qualification
testing and units are 100% RF tested.

Directivity
The impedance match of
the coupler to a 50Ω
system. Return Loss is an
alternate means to
express VSWR.
At a given frequency (ωn),
coupling is the input power
divided by the power at
the coupled port. Mean
coupling is the average
value of the coupling
values in the band. N is
the number of frequencies
in the band.
The input power divided
by the sum of the power at
the two output ports.
The input power divided
by the power at the direct
port.
The power at the coupled
port divided by the power
at the isolated port.
