KGF1321S
Power FET (Ceramic Package Type)
GENERAL DESCRIPTION
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.
FEATURES
• High output power: 31.5 dBm (min.)
• High efficiency: 70% (min.)
• Low thermal resistance: 18°C/W (typ.)
• Package: 3PFP
