DC0900B30
Directional Coupler
Rev A1
Description
The DC0900B30 is a low profile, high performance 30dB 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 355 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 ra¾o, the impedance match to 50Ω, the ideal value is 1:1.
Loss of signal power resul¾ng from the reflec¾on caused by discon¾nuity 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.
