Apparatus and method for IIP3 control for a wireless transceiver |
摘要 |
Disclosed is an apparatus for controlling the input 3<SUP>rd </SUP>order Intercept Point (IIP3) in a multi-mode multi-band wireless transceiver. The apparatus includes: a mixer for down-converting an incoming wireless signal which is received through each frequency band and is then low noise-amplified; a baseband chip for providing mixer IIP3 control information according to a current mode and transmission power level of the wireless transceiver; and a mixer IIP3 controller for controlling the IIP3 of the mixer based on the IIP3 control information. In a wireless transceiver without a band pass filter between a low noise amplifier and a mixer, the apparatus does not always increase the IIP3 of the mixer, but increases the IIP3 of the mixer in a wireless transceiver only when it is necessary to increase the IIP3. Therefore, the apparatus can reduce wasteful power consumption.
