Application Information
Layout Considerations
The wide bandwidth of the HA-5033 necessitates that high
frequency circuit layout procedures be followed. Failure to
follow these guidelines can result in marginal performance.
Probably the most crucial of the RF/video layout rules is the
use of a ground plane. A ground plane provides isolation and
minimizes distributed circuit capacitance and inductance
which will degrade high frequency performance. IC sockets
contribute inter-lead capacitance which limits device
bandwidth and should be avoided.
Pin 6 can be tied to either supply, grounded, or simply not used.
But to optimize device performance and improve isolation, it is
recommended that this pin be grounded.
Other considerations are proper power supply bypassing
and keeping the input and output connections as short as
possible which minimizes distributed capacitance and
reduces board space.
Power Supply Decoupling
For optimum device performance, it is recommended that
the positive and negative power supplies be bypassed with
capacitors to ground. Ceramic capacitors ranging in value
from 0.01µF to 0.1µF will minimize high frequency variations
in supply voltage. Solid tantalum capacitors 1µF or larger will
optimize low frequency performance.

It is also recommended that the bypass capacitors be
connected close to the HA-5033 (preferably directly to the
supply pins).
