Dimensions 3.7 x 3.5 x 2.4 inchesincluding connectors (94 x 89 x 60 mm)
Shipping dimensions 6.3 x 3.7 x 2.6 inches(160 x 95 x 65 mm)
Mounting Mounts using two screws(max. 5.5 mm diameter).
*VSWR and attenuation values are measured when the remainingports are terminated with 50 ohm loads.
The 3-dBcoupler can be used:
• As a decoupled power spliter with a ratio o 1:1
• For the decoupled combining o two transmitters with a
requency spacing as narrow as desired (at 3 dB loss)
• For the decouped combining o two receivers with requencyspacing as narrow as desired
• For the decoupled combining o two transmitter/receiver units,
whose integrated duplexers are within the same requency
range
• As a requency-independent 90° phase shiter
• As a component to orm combiners
Function:
The 3-dB coupler has our ports, two o which are decoupledrom each other. For example, eective power entering into
port 1 is distributed into ports 2 and 3. Port 4 is decoupled and
without power i ports 2 and 3 are ideally matched. In practicean absorber o suitable power at port 4 is to be planned in
accordance with the mismatch o ports 2 and 3.
Decoupled combining can be achieved via the diagonallyopposite ports 2 and 3 or 1 and 4.
For indoor or outdoor use (IP66).
