Provided is radio frequency integrated circuit(RFIC). The radio frequency integrated circuit (RFIC) comprises a plurality of transceiver IPs (intellectual property), wherein each transceiver IP includes an analog mixer configured to perform frequency adjustment on a signal input thereto, and a filter configured to perform filtering on the signal having the adjusted frequency based on a predetermined (or alternatively desired) band, a plurality of registers corresponding to the plurality of transceiver IPs, respectively; wherein the plurality of registers are configured to generate a plurality of control signals for controlling the plurality of transceiver IPs, respectively, a memory configured to store therein a plurality of register addresses and a plurality of register data on the plurality of registers, respectively in a form of a lookup table and a processor configured to receive a command related to the lookup table from an external component, and to control the plurality of registers based on the lookup table.

A radio module is configured to operate within a specialized frequency band, for example a band that has recently become available for use in the public domain. Superheterodyne techniques are used by a transmitter component of the radio module to frequency shift a conventional wireless data signal (e.g., used for WiFi, LTE telecommunications, etc.) into a designated band; a receiver component of the radio module is similarly configured to receive signals transmitted on the designated band and shift back into the conventional RF band (where standard components are able to further process the received signal).
