Buffers for Wireless Technology

The RF Transistor is a semiconductor device which can be used as an amplifier for high-power radio frequency signals. When an amplifier is used as a buffer, it has unity-gain; thus it only isolates signals between electrical nodes. An RF transistor configured as a buffer can isolate the driver from the load at radio frequencies.
