KGF2511
Midium Power Amplifier for UHF band
GENERAL DESCRIPTION
The KGF2511 is a midium power amplifier for UHF band that features high output power, high
linear gain, low distortion and low-current dissipation. The KGF2511 has specifications guaran-
teed by fixed matching circuit of 2.8V and 900MHz band, although external impedance matching
circuits are required. Because of the high output power and low distortion at the low operating
current, the KGF2511 is ideal as a transmitter driver stage amplifire for portable phones such as
PDC and CDMA.
FEATURES
• High output power: 8dBm (min)
• High linear gain: 27dB (min)
• Low distortion (ACP): –55dBc (max) @P
