The ACA1205 is a surface mount monolithic GaAs
RF Linear Amplifier that has been developed to
replace, in new designs, the standard CATV Hybrid
amplifiers currently in use. The MMIC consist of two

parallel amplifiers, each with 15 dB gain. The
amplifier is optimized for exceptionally low distortion
and noise figure while providing flat gain and
excellent input and output return loss.

Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these conditions.
Exposure to absolute ratings for extended periods of time may
adversely affect reliability.

Notes:

1. Pins 3 and 6 should be AC-coupled. No external DC bias should be
applied.

2. Pin 7 should be pulled to ground through resistor R1, as shown in Figure 3.
No external DC bias should be applied.

APPLICATION INFORMATION

The ACA1205 is designed as an input stage. This
part can be used alone for low gain, low output level
applications or can be cascaded with one of the
ACA0861 output stages for higher gain and output

signal drive level. The ACA1205 is a low power
dissipation part designed as a driver for the
ACA0861B output stage.
