PRELIMINARY
Hybrid Coupler
3 dB, 90
Description
The X3C25F1-03S 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, WIMAX applications. The X3C25F1-03S 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 25* 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.
