Model XC0450A-03
Rev B
Hybrid Coupler
3 dB, 90°
Description
The XC0450A-03 is a low profile, high performance 3dB hybrid coupler
in a new easy to use, manufacturing friendly surface mount package. It is
designed for NMT band applications. The XC0450A-03 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 45 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 (XC0450A-03P) and 6 of 6
RoHS compliant tin immersion (XC0450A-03S).

*Note: “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.

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 -55°C and 95°C. Based on
copper as well as dielectric losses, the insertion loss is
computed from -55°C to 300°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.
