Pico Xinger
20dB Directional Coupler
Description
The 1P620S Pico Xinger is a low profile, miniature 20dB directional coupler
in an easy to use surface mount package designed for MMDS and WLAN
applications. The 1P620S is for power and frequency detection as well as
power injection. The 1P620S is an ideal solution for the ever-increasing
demands of the wireless industry for smaller printed circuit boards and high
performance. Parts have been subjected to rigorous qualification testing
and units are 100% tested. They are manufactured using materials with x
and y thermal expansion coefficients compatible with common substrates.

COUPLING
Choice of a coupling value in an application normally
depends on the power level of the main (sampled) line.
For example, if the coupler is being used to monitor main
line power, the coupling value is selected to provide
sufficient power to the monitoring device and yet
minimize system loss. Note that any coupler reduces
power flowing in the main line by the amount coupled off;
a 10dB coupler reduces main line power by 1 dB (10%)
where a 20dB coupler reduces it by only 0.044dB (1%).
Anaren uses mean coupling and frequency sensitivity
with the coupling specification. The mean coupling value
is arrived at by periodically sampling the coupling value
over the specified band and averaging the readings.
Frequency sensitivity is the peak to peak variation in
coupling over the specified band.
VSWR & DIRECTIVITY
In directional couplers, directivity is specified in lieu of
isolation. Directivity is a measure of how well the coupled
power is isolated from reflections at the main line output
port. For example, open or short circuiting the output port
of a coupler with 20dB directivity would only affect the
coupled output power by 1% and only 0.1% for 30dB
directivity. High directivity is especially important if the
coupler is being used to measure the VSWR of a device
at its output port. In this application, accurate
measurements of forward and reverse power are
required.
In theory, VSWR and directivity characteristics of a
coupler are perfect; the input and output ports are
perfectly matched and no power is coupled to the isolated
port. In practice, factors associated with the design and
manufacturing processes limit VSWR and directivity. The
