ACA0861 – A, B, C, D

2

750/860 MHz CATV Line Amplifier MMIC

The ACA0861A and the ACA0861C are designed as

input stages and are specified at +34 dBmV flat output.

These parts 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 ACA0861A is a low power dissipation

part designed to drive the ACA0861B output stage. The

ACA0861C is a slightly higher power dissipation part and

provides the needed distortion parameters to drive the

ACA0861D output stage.

The ACA0861B and ACA0861D are designed as output

stages and are specified at + 44 dBmV flat output. These

parts can be used alone for low gain, high output level

applications or can be cascaded with one of the

ACA0861 input stages for higher gain. The ACA0861B is

a low power dissipation part designed as the output stage

with an ACA0861A input stage.

The ACA0861D is a

higher power dissipation part designed as the output

stage with an ACA0861C input stage. An ACA0861A and

ACA0861B

cascaded

provide

exceptional

push-pull

hybrid equivalent performance, an ACA0861C and

ACA0861D cascaded provide exceptional power doubling

hybrid equivalent performance (see Figure 2).

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 1 for test setup.

3.

All parts measured with 110 channel flat input. Parts A & C measured at +34 dBmV output. Parts B & D measured at 44 dBmV

output (per channel).

4.

A fixed resistor is needed for parts A through C, part D does not need an external resistor. These resistors set the devices’

current draw. Bias voltage is 12 VDC.
