The KGF2512 is a midium power amplifier for L-band that features high output power, high linear gain, low distortion and low-current dissipation. The KGF2512 has specifications guaranteed by fixed matching circuit of 2.8V and 1500MHz band, although external impedance matching circuits are required. Because of the high output power and low distortion at the low operating current, the KGF2512 is ideal as a transmitter driver stage amplifire for portable phones such as PDC.
