Model X3C25P1-05S
Rev B
5dB Directional Coupler
PRELIMINARY
Description
The X3C25P1-05S is a low profile, high performance 5dB directional
coupler in a new easy to use, manufacturing friendly surface mount
package. It is designed for DC, WCDMA, LTE and PCS applications.
The X3C25P1-05S is designed particularly for non-binary split and
combine in high power amplifiers, e.g. used along with a 3dB to get a 3-
way, plus other signal distribution applications where low insertion loss
is required. It can be used in high power applications up to 70 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

Mounting Interface Temperature ( C)
Temperature of the Part ( C)
Insertion Loss Derating:
The insertion loss, at a given frequency, of a group of
couplers is measured at 25C and then averaged. The
measurements are performed under small signal conditions
(i.e. using a Vector Network Analyzer). The process is
repeated at 95C and 150C. A best-fit line for the
measured data is computed and then plotted from -55C to
150C.
Power Derating:
The power handling and corresponding power derating
plots are a function of the thermal resistance, mounting
surface temperature (base plate 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.
If mounting temperature is greater than 95C, Xinger
coupler will perform reliably as long as the input power
is derated to the curve above.
