The KGF1608, housed in a SMD type ceramic package, is a discrete GaAs power FET that features high efficiency and high output power. The KGF1608 specifications are guaranteed to a fixed matching circuit for 3.4 V and 850 MHz; external impedance-matching circuits are also required. Because of its high efficiency (70% min.) , high output power (more than 33 dBm), the KGF1608 is ideal as a transmitter-final-stage amplifier for personal handy phones, such as 3-V digital cellular phones.
