Description
Hewlett–Packard’s ATF-21186 is a low cost Gallium Arsenide Schottky barrier-gate field effect transistor housed in a surface mount plastic package. This general purpose device is designed for use in low noise amplifiers, gain stages, driver amplifiers, and oscillators operating over the VHF, UHF, and microwave frequency ranges. High gain with two volt operation makes this part attractive for low voltage, battery operated systems. The low noise figure is appropriate for commercial systems demanding good sensitivity, such as GPS receiver front-ends and MMDS television receivers. The output power is sufficient for use as the driver stage in many hand-held transceivers operating in the 900␣ MHz through 2.4 GHz bands, including in cellular phones, PCN, and ISM band spread spectrum applications.
