Medium-Power Amplifier
GENERAL DESCRIPTION
The KGF1262 is a medium-power amplifier, with frequencies ranging from the UHF-band to the L-band, that features high gain, high output power, and low current operation. The KGF1262 specifications are guaranteed to a fixed matching circuit for 5.2 V and 1.9 GHz; external impedance-matching circuits are also required. Because of the high gain and high output power at the low operating current, the KGF1262 is ideal as a transmitter-driver amplifier for personal handy phones of more than 1.5 GHz band.
FEATURES
* High linear gain: 15 dB (min.) at 1.9 GHz * High output power: 18 dBm (min.) at 1.9 GHz * Low current operation: 70 mA (max.) * Self-bias circuit configuration with built-in source capacitor * package: 4PSOP
