KGF1323

Power FET(Plastic Package Type)

GENERAL DESCRIPTION

The KGF1323, housed in a SOT-89 type plastic-mold package, is a discrete UHF-band power FET
that features high efficiency and high output power. The KGF1323 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 33 dBm), and plastic
package, the KGF1323 is ideal as a transmitter-final-stage amplifier for personal handy phones,
such as TDMA-type cellular phones.

FEATURES

• High output power: 33 dBm (min.)

• High efficiency: 70% (typ.)

• Low thermal resistance: 23°C/W (typ.)

• Package: 3PMMP (SOT-89 type)
