ACA0861 - A, B, C, D
750/860 MHz CATV Line Amplier
MMIC
Data Sheet - Rev 2.3
PRODUCT DESCRIPTION
The ACA0861 family of surface mount monolithic
GaAs RF Linear Ampliers 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 Ampliers are optimized for exceptionally low
distortion and noise gure while providing at gain
and excellent input and output return loss. There
are four differently specied ampliers available: two
input stages and two output stages. The ACA0861A
and the ACA0861C are input stages and are
specied at +34 dBmV at output. The ACA0861B
and ACA0861D are output stages and are specied at
+44 dBmV at 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 specied at +34 dBmV at
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 specied at +44 dBmV at
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. Cascaded, an ACA0861A and ACA0861B
provide exceptional push-pull hybrid equivalent
performance; an ACA0861C and an ACA0861D
cascaded provide exceptional power doubling hybrid
equivalent performance.

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
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.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specications.
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 a resistor or left open-circuited. No
external DC bias should be applied.

(TA = +25 °C, VD = +12 VDC)
Notes:
(1) Measured performance of MMIC alone. Balun effects de-imbedded from measurement.
(2) Measured with a balun on input and output of the device. See Figure 3 for test setup.
(3) All parts measured with 110 channel at input. Parts A and C measured at +34 dBmV output (per channel).
Parts B and D measured at +44 dBmV output (per channel).
(4) A xed resistor is needed for parts A through C; part D does not need an external resistor (see Table 6.)
These resistors set the devices’ current draw. Bias voltage is +12 VDC.
