Document Type and Number:
WIPO Patent Application WO/2013/022241
Kind Code:
A3
Abstract:
A Radio Frequency (RF) amplifier in a communication system and a method for controlling the RF amplifier are provided. The RF amplifier includes an input unit for receiving an RF signal, a cascode unit for amplifying the RF signal according to a gain of the RF amplifier and for outputting the amplified RF signal, a load unit connected to the cascode unit, and a gain controller for controlling the gain by converting an impedance in a baseband to an impedance viewed from an RF band, the gain controller being connected in parallel to the load unit.
