HIGH ISOLATION BUFFER AMPLIFIER

Typical Applications

• Local Oscillator Buffer Amplifiers

• FDD and TDD Communication Systems

• Commercial and Consumer Systems

• Portable Battery-Powered Equipment

• Wireless LAN

• ISM Band Applications

Product Description

The RF2301 is a high reverse isolation buffer amplifier.

The device is manufactured on a low-cost Gallium Ars-

enide MESFET process, and has been designed for use

as a general purpose buffer in high-end communication

systems operating at frequencies from less than 300MHz

to higher than 2500MHz. With +5dBm output power, it

may also be used as a driver in transmitter applications.

The device is packaged in an 8-lead plastic package. The

product is self-contained, requiring just a resistor and

blocking capacitors to operate. The output power, com-

bined with 50dB reverse isolation at 900MHz allows

excellent buffering of LO sources to impedance changes.

The device can be used in 3V battery applications. The

unit has a total gain of 17dB with only 14mA current from

a 3V supply.
