20dB Directional Coupler
t
Description
The XC2500P-20S is a low profile, high performance 20dB directional
coupler in a new easy to use, manufacturing friendly surface mount
package. It is designed for AMPS band applications. The XC2500P-20S is
designed particularly for power and frequency detection, as well as for
VSWR monitoring, where tightly controlled coupling and low insertion loss
is required. It can be used in high power applications up to 50 Watts.
Parts have been subjected to rigorous qualification testing and they are
manufactured using materials with coefficients of thermal expansion (CTE)
compatible with common substrates such as FR4, G-10, RF-35, RO4003
and polyimide. Produced with 6 of 6 RoHS compliant tin immersion finish.

Insertion Loss Derating:
The insertion loss, at a given frequency, of a group of
couplers is measured at 25°C and then averaged. The
measurements are performed under small signal
conditions (i.e. using a Vector Network Analyzer). The
process is repeated at 95°C, 150°C, and 200°C. A best-
fit line for the measured data is computed and then
plotted from -55°C to 300°C.
Power Derating Based on Solder Type:
The power derating plots above are a function of the thermal
resistance, mounting interface temperature, maximum continuous
operating temperature of the coupler, thermal insertion loss, and
the maximum operating temperature of the solder type used for
mounting. The thermal insertion loss is defined in the Power
Handling section of the data sheet.
As the mounting interface temperature approaches the maximum
continuous operating temperature of the coupler or the maximum
operating temperature of the solder, the power handling decreases
to zero.
