Abstract
A cascaded RF system includes a first MMIC and at least a second MMIC. During a first mode of operation: using an LO generation circuit of the first MMIC to generate a first LO signal based on a system clock signal; outputting the first LO signal from an LO output port of the first MMIC; receiving the first LO signal via a first LO input port of the first MMIC; and receiving the first LO signal via a second LO input port of the second MMIC. During a second mode of operation: using an LO generation circuit of the second MMIC to generate a second LO signal based on the system clock signal; and outputting the second LO signal from an LO output port of the second MMIC to a first LO input port of the second MMIC and to a second LO input port of the first MMIC.
