1998 KGF1284 ¡ electronic components 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.
