20dB Directional Coupler
t
Description
The XC1500A-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 XC1500A-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 160 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, RO4350
and polyimide. Produced with 6 of 6 RoHS compliant tin immersion finish.

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.
Power Derating:
The power handling and corresponding power derating
plot is a function of the thermal resistance, mounting
interface temperature, maximum continuous operating
temperature of the coupler, and the thermal insertion
loss. 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, the power
handling decreases to zero.
This power derating does not take into account the type
of solder used for mounting the part to the substrate.
