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).

Power Handling
The average power handling (total input power) of a Xinger coupler is a function of:
• Internal circuit temperature.
• Unit mounting interface temperature.
• Unit thermal resistance
• Power dissipated within the unit.
All thermal calculations are based on the following assumptions:
•
•
•
•
•
www.DataSheet4U.co•m
The unit has reached a steady state operating condition.
Maximum mounting interface temperature is 95oC.
Conduction Heat Transfer through the mounting interface.
No Convection Heat Transfer.
No Radiation Heat Transfer.
The material properties are constant over the operating temperature range.
Finite element simulations are made for each unit. The simulation results are used to calculate the unit thermal
resistance. The finite element simulation requires the following inputs:
• Unit material stack-up.
• Material properties.
• Circuit geometry.
• Mounting interface temperature.
• Thermal load (dissipated power).
The classical definition for dissipated power is temperature delta (ΔT) divided by thermal resistance (R). The
dissipated power (Pdis) can also be calculated as a function of the total input power (Pin) and the thermal insertion loss
(ILtherm):
