Description
The DC1900P05 is a low profile, high performance 5dB directional coupler.
It is designed for DCS and PCS applications. This component is suitable
for 3 way power divide & combine circuits where low insertion loss, high
directivity is required. It can be used in power applications up to 35 Watts.
Parts have been subjected to rigorous qualification testing and they are
using materials with coefficients fo thermal expansion(CTE) compatible
with common substrates such as FR4, G-10, RF-35, RO4350B and
polyimide.

Description
Voltage standing wave raîo, the impedance match to 50Ω, the ideal value is 1:1.
Loss of signal power resulîng from the reflecîon caused by disconînuity of transmission line.
The input power divided by sum of power at the coupling port & transmission port.
The input power divided by the power at coupling port.
The input power divided by the power at transmission port.
The power at the coupling port divided by the power at the isolated.
The difference between coupling port and transmission port.
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 return loss port 1, port 2, port 3 & port 4.
7. According to the above data to calculate insertion loss, directivity
and phase balance.
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 :
