General Description
The RF2312 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 75Ω gain block. In
addition to the high linearity, the gain flatness of better
than 0.5ꢀdB from 5ꢀꢀ–ꢀ725ꢀMHz, makes this part ideal for
cable TV Return Path FDX applications. The device is
self-contained with 75Ω input and output impedances
and requires only two external DC biasing elements to
operate as specified.

Description
RF input pin. This pin is NOT internally DC-blocked. A DC-blocking capacitor, suitable for the
frequency of operation, should be used in all applications. The device has internal feedback, and
not using a DC blocking capacitor will disable the temperature compensation. The bias of the device
can be controlled by this pin. Adding an optional 1kΩ resistor to ground on this pin reduces the bias
level, which may be compensated for by a higher supply voltage to maintain the appropriate bias
level. The net effect of this is an increased output power capability, as well as higher linearity for
signals with high crest factors. DC-coupling of the input is not allowed, because this will override the
internal feedback loop and cause temperature instability.

Ground connection. For best performance, keep traces physically short and connect immediately
to ground plane. Each ground pin should have a via to the ground plane.

RF output and bias pin. Because DC is present on this pin, a DC-blocking capacitor, suitable for the
frequency of operation, should be used in most applications. For biasing, an RF choke in series with
a resistor is needed. The value for the resistor RC is 30ꢀΩ (0.5ꢀW) for VCC=9ꢀV and 21ꢀΩ for VCCꢀ=ꢀ8ꢀV.
The DC voltage on this pin is typically 6.0ꢀV with a current of 100ꢀmA. In lower power applications
the value of RC can be increased to lower the current and VD on this pin.
