PRODUCT DESCRIPTION
The ACA0862 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 ACA0862 can also
replace the ACA0861 with the addition of tuning
capacitors to the output (see Figure 3). 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. The ACA0862B
and ACA0862D are optimized for different output
powers, and can be used separately or cascaded to
support a variety of applications. A Hybrid equivalent
is formed when two ACA0862 devices are cascaded
between transmission line baluns. For low gain
applications a single ACA0862 can be used; for higher
gain applications more than two can be cascaded. See
the ACA0861 application note for more information.

Output Stages
The ACA0862B and ACA0862D are designed as output
stage amplifiers. These parts can be used alone for
low gain, high output level applications or can be
cascaded with an ACA1206 input stage amplifier for
higher gain. The ACA0862B is a low power dissipation
part, while the ACA0862D is a higher power dissipation
part. Cascaded, an ACA1206 and ACA0862B provide
exceptional push-pull hybrid equivalent performance;
an ACA1206 and an ACA0862D cascade provides
exceptional power doubling hybrid equivalent
performance. An ACA0862B can also be cascaded
with an ACA0862D to create a power doubler with
even better distortion performance.

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.
Notes:
(1) Pins 3 and 6 should be AC-coupled. No external DC bias should be
applied.
(2) Pin 7 must be terminated through a resistor to either Vd or GND.
