Model X3C26P1-30S
Rev A
30 dB Directional Coupler
Description
The X3C26P1-30S is a low profile, high performance 30dB directional
coupler in a new easy to use, manufacturing friendly surface mount
package. It is designed for WIMAX and LTE band applications. The
X3C26P1-30S 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 200 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

Directional Coupler Pin Configuration
The X3C26P1-30S has an orientation marker to denote Pin 1. Once port one has been identified the other ports are
known automatically. Please see the chart below for clarification:

Note: The direct port has a DC connection to the input port and the coupled port has a DC connection to the
isolated port.
For optimum IL and power handling performance, use Pin 1 or Pin 2 as inputs.

Temperature of the Part ( C)
Mounting Interface Temperature ( C)
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 85°C and 150°C. A best-fit line for
the measured data is computed and then plotted from -
55°C to 150°C.
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 95°C, Xinger
coupler will perform reliably as long as the input power is
derated to the curve above.
