GENERAL PURPOSE
AMPLIFIERS
The RF2310 is a general purpose, low-cost, high linearity
RF amplifier IC. The device is manufactured on an
advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as
an easily cascadable 50Ω gain block. Applications
include IF and RF amplification in wireless voice and data
communication products operating in frequency bands up
to 2500MHz. The gain flatness over a very wide bandwidth makes the device suitable for many applications.
The device is self-contained with 50Ω input and output
impedances and requires only two external DC biasing
elements to operate as specified.

Description
Interface Schematic
Power supply pin. An external bypass capacitor is recommended. The
total supply current is shared between this pin and pin 8 (through the
inductor).
VCC
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
To achieve the performance as specified, and to minimize instability, it
is recommended to have a local ground plane under the device, as
shown in the evaluation board layout.
Same as pin 2.
RF input pin. This pin is NOT internally DC-blocked. A DC-blocking
capacitor, suitable for the frequency of operation, should be used in
most applications. DC-coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instability.

RF output and bias pin. Biasing is accomplished with an external choke
inductor to VCC that provides high impedance at the operating frequency. Because DC is present on this pin, a DC-blocking capacitor,
suitable for the frequency of operation, should be used in most applications. The supply side of the bias network should also be well
bypassed.
