Notes :
(1)
Typical values are nominal performances at room temperature
(2)
No matching circuit is 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. Port 1 is loaded on 50
, while ports 2 and 3 are loaded on 50
