Product Description
The RF2320 is a general purpose, low-cost, high-linearity RF amplifier IC. The
device is manufactured on a Gallium Arsenide process and is featured in an SOP16 batwing package. It has been designed for use as an easily cascadable 75Ω
gain block with a noise figure of less than 2dB. Gain flatness better than 0.5dB
from 5MHz to 1000MHz, and high linearity make this part ideal for cable TV applications. Other applications include IF and RF amplification in wireless voice and
data communication products operating in frequency bands up to 2500MHz. The
device is self-contained with 75Ω input and output impedances providing 2:1
VSWR matching. For higher input and output return losses, see the evaluation schematic.

Ground connection. Keep traces physically short and connect immediately

RF input pin. This pin is not internally DC blocked. A DC blocking capacitor
suitable for the frequency of operation is required if DC is present from the
previous stage. The gate voltage is nominally 0V but can be raised externally to increase the bias level. This will increase the current drain but
improve linearity.

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, only an RF choke is needed.
