Description
The DC1900P10 is a low profile, high performance 10dB directional
coupler. It is designed for DCS & PCS applications. This component is
suitable for feed-forward amplifier and signal sampling circuits where low
insertion loss, high directivity is required. It can be used in power
applications up to 20 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 ra2o, the impedance match to 50Ω, the ideal value is 1:1.
Loss of signal power resul2ng from the reec2on caused by discon2nuity 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.
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 2(S21).
5. Measure the data of isolation through port 1 to port 3(S31).
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.
Note:
1. When calculating insertion loss at room termperature,
coupling & transmission data both need remove demo board loss.
