750/870 MHz CATV Line Amplifier

Data Sheet - Rev 2.1

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

•Low Cost

•Repeatability of Monolithic Fabrication

•Meets Cenelec Standard

•RoHS-Compliant Package Option

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.

Notes:

(1) Measured performance of MMIC alone. Balun effects deimbedded from measurement.

(2) Measured with a balun on input and output of the device. See Figure 3 for test setup.

(3) Part measured with 110 channel flat input, +34 dBmV output (per channel).

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.
