Abstract: An apparatus, and method therefor, relate generally to broadband IQ generation. In this apparatus, related generally to broadband in-phase and quadrature phase (“IQ”) generation, a divider circuit and a polyphase filter circuit are configured for receiving an oscillator output. The polyphase filter circuit is configured for polyphase filtering the oscillator output into a first quadrature output. The divider circuit is configured for dividing the oscillator output into a second quadrature output. A multiplexer circuit is coupled to the divider circuit and the polyphase filter circuit and configured for selecting either the first quadrature output or the second quadrature output as an IQ output based on a bandwidth of the oscillator output.
