Description:

The ACA0862 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 ACA0862 can also replace the ACA0861 with the addition of tuning capacitors to the output (see Figure 3). The MMICs 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 three differently specified amplifiers available: one input stage and two output stages. The ACA0862C is an input stage and is specified at +34 dBmV flat output. The ACA0862B and ACA0862D are output stages and are specified at higher output power levels. A Hybrid equivalent is formed when one input stage ACA0862 is cascaded with an ACA0862 output stage between two transmission line baluns. For low gain applications a single ACA0862 can be used between baluns, for higher gain applications more than two ACA0862 can be cascaded between baluns. See ACA0861 application note for more information.
