electronic components KGF1631
Power FET (Plastic Package Type)
GENERAL DESCRIPTION
The KGF1631, housed in a SOT-89 type plastic-mold package, is a discrete GaAs power FET that features high efficiency and high output power. The KGF1631 specifications are guaranteed to a fixed matching circuit for 3.4 V and 850 MHz; external impedance-matching circuits are also required. The KGF1631 provides an output power of more than 24dBm at 3.4V, with high efficiency (50% typ.) and high gain (21dB typ.). The device is optimized for transmitter driver amplifier applications for Portable Handy Phones (PHPs) and other 3-V cellular phones. FEATURES * High output power: 24 dBm (min.) * High gain: 21dB (typ.) * High efficiency: 50% (typ.) * Specifications guaranteed to a fixed matching circuits for 3.4 V, 850 MHz * Package: 3PMMP (SOT-89 type)
