Classification: CPC H | IPC H

Claim 9:
10. A receive in-phase quadrature (IQ) amplifier, comprising:
an in-phase (I) phase switching gain stage to receive an I component of an input signal and to generate an amplified phase switching I signal;
a quadrature (Q) phase switching gain stage to receive a Q component of the input signal and to generate an amplified phase switching Q signal;
an in-phase quadrature (IQ) poly-phase filter coupled to the I and Q phase switching gain stages to receive the amplified phase switching I and Q signals and outputs a balanced signal; and
a common gain stage coupled to the IQ poly-phase filter to receive the balanced signal from the IQ poly-phase filter and outputs an amplified balanced signal,
wherein the I or Q phase switching gain stage comprises a passive phase switching component or an active phase switching component.
