AD8354
APPLICATIONS
The AD8354 RF gain block can be used as a general-purpose,
fixed gain amplifier in a wide variety of applications, such as a
driver for a transmitter power amplifier (see Figure 37). Its
excellent reverse isolation also makes this amplifier suitable for
use as a local oscillator buffer amplifier that would drive the
local oscillator port of an upconverter or downconverter mixer
(see Figure 38).

LOW FREQUENCY APPLICATIONS BELOW 100 MHz
The AD8354 RF gain block can be used below 100 MHz. To
accomplish this, the series dc blocking capacitors, C1 and C2,
need to be changed to a higher value that is appropriate for the
desired frequency. C1 and C2 were changed to 0.1 μF to accomplish
the sweeps in Figure 39.
