HC1400A03
Hybrid Coupler 3 dB, 90 o
Rev B2
Description
The HC1400A03 is a low profile, high performance 3dB hybrid coupler
in a new easy to use, manufacturing friendly surface mount package. It is
designed for GPS band applications. The HC1400A03 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 150Watts.

*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.

The impedance match of
the coupler to a 50W

an alternate means to
express VSWR.
The input power divided
by the sum of the power
at the two output ports.
The input power divided
by the power at the
isolated port.
The difference in phase
angle between the two
output ports.
The power at each output
divided by the average

Test Method
1. Calibrating your vector network analyzer.
2. Connect the VNA 4 Port to DUT respectively.
3. Measure the data of coupling through port 1 to port 4(S41).
4. Measure the data of transmission through port 1 to port 3(S31).
5. Measure the data of isolation through port 1 to port 2(S21).
6. Measure the data of phase port 4 & port 3(port 1 feeding).
7. Measure the data of return loss port 1, port 2, port 3 & port 4.
8. According to the above data to calculate insertion loss,
amplitude balance & phase.
