(as illustrated in the curves), the maximum bandwidth is
obtained without sacrificing stability. Even so, bandwidth
does decrease as you move to the right along the curve.
For example, at AV = +1, RS = 50, CL = 30pF, the overall
bandwidth is limited to 300MHz, and bandwidth drops to
100MHz at AV = +1, RS = 5, CL = 340pF.
Evaluation Board
The performance of the HFA1112 may be evaluated using
the HFA11XX Evaluation Board, slightly modified as follows:
1. Remove the 500
feedback resistor (R
2), and leave the
connection open.
2. a. For AV = +1 evaluation, remove the 500 gain setting
resistor (R1), and leave pin 2 floating.
b. For AV = +2, replace the 500 gain setting resistor with
a 0
resistor to GND.
The layout and modified schematic of the board are shown in
Figure 2.
To order evaluation boards (part number HFA11XXEVAL),
please contact your local sales office.
