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 SOP-16 batwing
package. It has been designed for use as an easily cas-
cadable 75
gain block with a noise figure of less than
2 dB. Gain flatness better than 0.5dB from 5MHz to
1000 MHz, 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 75
input and output
impedances providing 2:1 VSWR matching. For higher
input and output return losses, see the evaluation sche-
matic.

No connection. This pin should be connected to the ground plane.
2
NC
Same as pin 1.
3
GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance. Each ground pin should
have a via to the ground plane.
4
GND
Same as pin 3.
5
GND
Same as pin 3.
6
RF IN
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 block-
ing capacitor, suitable for the frequency of operation, should be used in
most applications. For biasing, only an RF choke is needed.
