Classification: CPC H | IPC H

Claim 0:
1. A transmit in-phase quadrature (IQ) amplifier, comprising:
a common gain stage to receive an input signal and to generate an amplified signal;
an in-phase quadrature (IQ) poly-phase filter coupled to the common gain stage to receive the amplified signal from the common gain stage and outputs a four-phase signal;
an in-phase (I) phase switching gain stage coupled to the IQ poly-phase filter to receive I components of the four-phase signal and outputs an amplified phase switching I signal; and
a quadrature (Q) phase switching gain stage coupled to the IQ poly-phase filter to receive Q components of the four-phase signal and outputs an amplified phase switching Q signal,
wherein the I or Q phase switching gain stage comprises a passive phase switching component or an active phase switching component.
