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.
