Notes :
(1) : Typical values are nominal performances at room temperature .
(2) : No external matching circuit required.
(3) : The amplitude variation is defined as the maximum level – minimum level over the given bandwidth.
(4) : The output balance is defined as the S parameters ratio -(S31 / S21), where the port 1 is the input port and the
ports 2 and 3 are the balanced output. The parallel inductance is connected between ports 2 and 3. Port 1 is loaded
on 50
, while ports 2 and 3 are loaded on 75
each.
