Hybrid Coupler
3 dB, 90
Description
The X3C21P1-03S is a low profile, high performance 3dB hybrid coupler in a
new easy to use, manufacturing friendly surface mount package. It is
designed for LTE and WIMAX band applications. The X3C21P1-03S is
designed particularly for balanced power and low noise amplifiers, plus
signal distribution and other applications where low insertion loss and tight
amplitude and phase balance is required. It can be used in high power
applications up to 110 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.

*Notes: “A” is the amplitude of the applied signals. When two quadrature signals with equal amplitudes are
applied to the coupler as described in the table, they will combine at the output port. If the amplitudes are
not equal, some of the applied energy will be directed to the isolated port.
The actual phase,
, or amplitude at a given frequency for all ports, can be seen in our de-embedded s-
parameters, that can be downloaded at www.anaren.com.

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 85C, 150C, and 200C. A best-
fit line for the measured data is computed and then
plotted from -55C to 300C.
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.
