XC1900A-20 Datasheet, PDF (1/22 Pages) Anaren Microwave – 20 dB Directional Coupler

Model XC1900A-20
Rev D
20 dB Directional Coupler
Description
The XC1900A-20 is a low profile, high performance 20dB directional
coupler in a new easy to use, manufacturing friendly surface mount
package. It is designed for DCS and PCS band applications. The
XC1900A-20 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
150 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. Available in both 5 of 6 tin lead (XC1900A-20P) and 6 of 6
tin immersion (XC1900A-20S) RoHS compliant finishes.
