Abstract: Disclosed herein a source routing apparatus and method in ICN. The method includes: receiving an interest packet; extracting a current entry value when the received interest packet includes a forwarding hint; using the extracted current entry value as an index of a path list; extracting a name of the interest packet; reducing the current entry value when the interest packet is transmitted to a network area of the path list; performing a FIB lookup with the extracted name; determining an output port using the FIB lookup; and transmitting the interest packet to the output port.

Abstract: Disclosed is a dual-band phase shifter in which series/parallel resonance circuits are applied to a polyphase filter to implement a phase shifter, which is a core block of a multi-channel RFIC for implementing a phased array antenna system. The dual-band phase shifter may be configured by converting a capacitor (C) of an LC circuit or a CL circuit in the RFIC into a series resonance circuit and converting an inductor (L) thereof into a parallel resonance circuit, so that a signal generator operating in one frequency band can operate in a dual-band.
