Processing signals by couplers embedded in an integrated circuit package
摘要:
Methods and systems for processing signals via directional couplers embedded in a package are disclosed and may include generating via a directional coupler, one or more output RF signals that may be proportional to a received RF signal. The directional coupler may be integrated in a multi-layer package. The generated RE signal may be processed by an integrated circuit electrically coupled to the multi-layer package. The directional coupler may include quarter wavelength transmission lines, which may include microstrip or coplanar structures. The directional coupler may be electrically coupled to one or more variable capacitances in the integrated circuit. The variable capacitance may include CMOS devices in the integrated circuit. The directional coupler may include discrete devices, which may be surface mount devices coupled to the multi-layer package or may be devices integrated in the integrated circuit. The integrated circuit may be flip-chip bonded to the multi-layer package.
