ACA0861 - A

The ACA0861 family of surface mount monolithic GaAs RF Linear Amplifiers has been developed to replace, in new designs, the standard CATV Hybrid amplifiers currently in use.  The MMICs ACA0861 consist of two parallel amplifiers, each with  12 dB gain.  The Amplifiers are optimized for exceptionally low distortion and noise figure while providing flat gain and excellent input and output return loss.  There are four differently specified Amplifiers available, two input stages and two output stages. The ACA0861A and the ACA0861C are input stages and are specified at +34  dBmV flat output. The ACA0861B and ACA0861D are output stages and are specified at +44 dBmV flat output.   A Hybrid equivalent is formed when one input stage ACA0861 is cascaded with an ACA0861 output stage between two transmission line baluns.  For low gain applications a single ACA0861 can be used between baluns, for higher gain applications more than two ACA0861 can be cascaded between baluns. See ACA0861 application note for more information.
