HC1900E03
Hybrid Coupler 3 dB, 90o
Rev B0
Description
The HC1900E03 is a low profile, high performance 3dB hybrid coupler
in a new easy to use, manufacturing friendly surface mount package. It is
designed for DCS & PCS band applications. The HC1900E03 is
particularly for balanced power and low noise amplifiers, plus signal
designed 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 120 Watts.
Orientation Marker
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.

Definition of Measured Specifications
Parameter
VSWR
(Voltage Standing Wave
Ratio)
Definition
The impedance match of
the coupler to a 50W
system. A VSWR of 1:1 is
optimal.
Mathematical Representation
Vmax
VSWR =
Vmin
Vmax = voltage maxima of a standing wave
Vmin = voltage minima of a standing wave
Return Loss
Insertion Loss
Isolation
Phase Balance
The impedance match of
the coupler to a 50W
system. Return Loss is
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.

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.
Note:
1. When calculating insertion loss at room temperature,
demo board loss should be removed from both coupling & transmission data.
Please refer to the below table for demo board loss :
