The RF2322 is a general purpose, low-cost silicon ampli-
fier designed for operation from a 3V supply. The circuit
configuration with resistive feedback allows for broad-
band cascadable amplification. Capacitive compensation
extends the bandwidth of the amplifier and input stage
design optimizes noise figure. The device is uncondition-
ally stable and internally matched to 50
. The only exter-
nal components required for specified performance are
bypass and DC blocking capacitors (as shown in applica-
tion schematic). The RF2322 is available in a very small
industry-standard SOT-23 5-lead surface mount package,
enabling compact designs which conserve board space.

Function
Description
Interface Schematic
1
GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
2
GND
Same as pin 1.
3
RF IN
RF input pin. This pin is not internally DC blocked and thus requires an
external blocking capacitor suitable for the frequency of operation. The
input impedance of this pin is internally matched to 50
using resistive
feedback.
4
VCC
Supply connection. This pin should be bypassed with a suitable capac-
itor(s).
5
RF OUT
RF output and bias pin. The output impedance of this pin is internally
matched to 50
using resistive feedback. Because DC biasing is
present on this pin, a DC blocking capacitor should be used in most
applications (see application schematic).
See pin 3 schematic.
