Description:
The 1X503 is a low profile, miniature 3dB hybrid
coupler in an easy to use surface mount package
designed for DCS and PCS applications. The 1X503
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 run
through 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

2400
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 typical two to three degrees maximum
although in practice, phase balance is statistically better
than specified (<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 the internal meandered circuit traces as
well as limitations of building perfect 50transitions at
the input and output ports of the device. Typically,
VSWR and isolation of 1.15:1 and 25 dB respectively are
achieved in practice.
INSERTION LOSS
Coupler insertion loss is defined as the difference of the
input power from the sum of the output power. In
