KGF1637
Power FET (Plastic Package Type)
GENERAL DESCRIPTION
The KGF1637, housed in a SOT-89 type plastic-mold package, is a discrete GaAs power FET that
features high efficiency and high output power. The KGF1637 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 more than 70 %, high output power (more than 31.5 dBm),
and plastic package, the KGF1637 is ideal as a transmitter-final-stage amplifier for personal
handy phones, such as 3-V analog cellular phones.
