The RF2301 is a high reverse isolation buffer amplifier. The device is manufactured on a low-cost Gallium Arsenide 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, combined 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.
