Abstract
This paper presents a dual-mode amplifier which operates as amplifier or frequency multiplier according to the input frequency. It satisfies the 802.11a/b/g frequency band of wireless LAN standard. A conventional dual-band wireless LAN transmitter consists of the separating power amplifiers operating at each frequency band, but the proposed dual-mode amplifier operates as an amplifier for the 802.11b/g signal and as a frequency multiplier for the 802.11a signal according to each LAN bias condition. The amplifier mode shows the gain of 13dB, the PldB of 17dBm and second harmonic suppression of below -37dBc. And the frequency-doubler mode shows the gain of 3.3dB, the output power of 7.3dBm and third harmonic suppression of below -50dBr.
