1 ev B1 Description The is a low profile, high performance 10dB directional coupler. It is designed for WCDMA & 3G 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 F4, G-10, F-35, O4350B and polyimide. Orientation Marker Part No. Signal Pad GND Features: MHz WCDMA & 3G Low Insertion Loss High Directivity Low VSW Good epeatability CTE compatible with F4, G-10, F-35, O4350B and polyimide Immersion gold, prevent surface oxidation & scratch ohs Compliant Tape & eel Package available Mechanical Outline Electrical Specifications Frequency Coupling Directivity VSW MHz db db Min Max : ± Insertion Loss Power Operating Temp. db Max Avg.

5 ev B1 Description of Measured Specifications Parameter Description VSW Voltage standing wave ra.o, the impedance match to 50Ω, the ideal value is 1:1. eturn Loss Loss of signal power resul.ng from the reflec.on caused by discon.nuity of transmission line. Insertion Loss The input power divided by sum of power at the coupling port & transmission port. Coupling The input power divided by the power at coupling port. Transmission The input power divided by the power at transmission port. Directivity 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 According to the above data to calculate insertion loss, directivity. Vector Network Analyzer Port 1 Port 2 Port 3 Port 4 Note: 1. When calculating insertion loss at room termperature, coupling & transmission data both need remove demo board loss.
