KGF1284

Power FET (Plastic Package Type)

GENERAL DESCRIPTION

The KGF1284, housed in a SOT-89 type plastic-mold package, is a discrete power FET with

frequencies ranging from the UHF-to L-band. This device features high efficiency, high output

power, and high gain. The KGF1284 specifications are guaranteed to a fixed matching circuit for

3.4 V and 1.9 GHz; external impedance-matching circuits are also required. Because of its high

efficiency, high output power (more than 21.5 dBm), high gain, and plastic package, the KGF1284

is ideal as a transmitter-driver amplifier for personal handy phones, such as digital keying

cordless phones.

FEATURES

• Specifications guaranteed to a fixed matching circuit for 3.4 V, 1.9 GHz

• High output power: 21.5 dBm (min.) at 1.9 GHz

• High efficiency: 50% (typ.) at 1.9 GHz

• High linear gain: 12 dB (typ.) at 1.9 GHz

• Package: 3PMMP (SOT-89 type)
