9. Test Method
- Refer to ‘Case 1’ of ‘4. Port Configuration’ on page 4
- Have the network analyzer calibrated properly.
- Measure the data of Coupling through port 1 to port 3. (S31)
- Measure the data of Transmission through port 1 to port 4. (S41)
- Measure the data of Isolation through port 1 to port 2. (S21)
- Calculate the Insertion Loss and Amplitude Balance of coupler on the below power method formula.

13. Using note for LTCC Couplers
I.Be careful when transporting
A.Excessive stress or shock may make products broken or cracked due to the nature of
ceramics structure.
B.The products cracked or damaged on terminals may have their property changed.
II.Be careful during storage
A.Store the products in the temperature of -55 ~ 125℃
B.Keep the humidity at 45 ~ 75% around the products.
C.Prevent corrosive gas (Cl2, NH3, SO X, NO X, etc.) from contacting the products.
D.It is recommended to use the products within 6 months of receipt. If the period exceeds
6 months, solderability may need to be verified.
III.Be careful when soldering
A.All the ground terminals, IN and OUT pad of coupler should be soldered on the ground
plane of the PCB.
B.Products may be cracked or broken by uneven forces from a claw or suction device.
C.Mechanical stress by any other devices may damage products when positioning them on
PCB.
D. A dropped product is recommended not to be used.
E.Soldering must be carried out by the condition of specification sheet.
F.Any couplers which are de-soldered from PCB should not be used again.
