Data Sheet - Rev 2.0
FEATURES
15 dB Gain
Very Low Distortion
Excellent Input/Output Match
Low DC Power Consumption
Good RF Stability with High VSWR
Load Conditions
Surface Mount Package Compatible
with Automatic Assembly

APPLICATIONS
CATV Distribution Amplifier
High Linearity CATV Amplifier
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.
The device may be operated safely over these conditions; however,
parametric performance is guaranteed only over the conditions defined in
the electrical specifications.

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.

Notes:
1. T1, T2 (balun) wind 4 turns thru core as shown. (Figure 14).
2. N connector,center pin,should be approximately 80 mils in length.
3. Due to the high power dissapation of this devide the PC board should be mounted/ attached to a large heat
sink.
