ACA0861 — A, B, C, D
750/860 MHz CATV LINE AMPLIFIER MMIC
Advanced Product Information
Rev 2
DESCRIPTION
The ACA0861 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 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
four differently specified Amplifiers available, two
input stages and two output stages. The ACA0861A
and the ACA0861C are input stages and are specified
at +34 dBmV flat output. The ACA0861B and
ACA0861D are output stages and are specified at +44
dBmV flat output. A Hybrid equivalent is formed
when one input stage ACA0861 is cascaded with an
ACA0861 output stage between two transmission line
baluns. For low gain applications a single ACA0861
can be used between baluns, for higher gain
applications more than two ACA0861 can be
cascaded between baluns. See ACA0861 application
note for more information.

INPUT STAGES
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.
OUTPUT STAGES
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.
