The KGF1321S, housed in a SMD-type ceramic package, is a discrete UHF-band power FET that features high efficiency, high output power, and low current operation. The KGF1321S specifications are guaranteed to a fixed matching circuit for 5.8 V and 850 MHz; external impedance-matching circuits are also required. Because of its high efficiency, high output power (more than 31.5 dBm), and SMD package, the KGF1321S is ideal as a transmitter-final-stage amplifier for personal handy phones, such as analog cellular phones.
