Model 1C403
Rev. B
Hybrid Couplers
3 dB, 90°
Description
The 1C403 is a low profile, miniature 3dB hybrid coupler in an easy to use
surface mount package designed for AMPS applications. The 1C403 is
designed for balanced amplifiers and signal distribution and is an ideal
solution for the ever-increasing demands of the wireless industry for smaller
printed circuit boards. Parts have been subjected to rigorous qualification
testing and units are 100% tested. They are manufactured using materials
with x and y thermal expansion coefficients compatible with common
substrates such as FR4, G-10 and polyamide.

AMPLITUDE BALANCE
3dB hybrids are a type of backward wave coupler. In
the design of these couplers, the even mode
impedance was chosen to ‘critically couple’ or slightly
‘over couple’ at mid band to maximize performance and
bandwidth. The amplitude balance specification is
defined as the decibel difference between the two
output curves.
PHASE BALANCE
In theory, output ports of a backward wave hybrid
coupler remain in perfect phase quadrature
independent of frequency. In practice, factors
associated with the manufacturing processes slightly
degrade performance. The specification is typically two
to three degrees maximum. In practice, phase is
statistically better than the specified value (<1o).

VSWR & ISOLATION
Similar to phase balance, the VSWR and isolation of
a coupler are theoretically perfect; where the input
and output ports are perfectly matched and no power
is coupled to the isolated port. In practice, factors
associated with the design and manufacturing
processes limit VSWR and isolation. The significant
limitations are associated with limitations of building
perfect 50transitions at the input and output ports
of the device.
INSERTION LOSS
Coupler insertion loss is defined as the difference of
the input power from the sum of the output power. In
practice, loss is typically 0.20 dB. Specification limits
are somewhat higher due to imperfect test
conditions; as the couplers must be tested in fixtures
that negatively affect results.
