    Abstract: An electronic device for synthesizing a frequency is provided. The electronic device includes a bank changer configured to output a channel code corresponding to a reference frequency signal and a feedback frequency signal, a channel code mapper configured to generate a changed channel code by applying an offset to the channel code output from the bank changer, and a voltage controlled oscillator configured to control a total capacitance of a plurality of capacitors based on the changed channel code and to oscillate a frequency dependent on the total capacitance.

    Abstract: A radio frequency (RF) apparatus includes a radio frequency integrated circuit (RFIC) chip and an antenna module disposed on an upper surface of the RFIC chip. The antenna module includes a first antenna patch that is in parallel with the RFIC chip, the first antenna patch including a first penetration point, and a first power feed point connected to a first power feed line to transmit and receive a first RF signal of a first frequency band; and a second antenna patch disposed above the first antenna patch in parallel with the first antenna patch, the second antenna patch including a second power feed point connected to a second power feed line that penetrates through the first penetration point to transmit and receive a second RF signal of a second frequency band. The first penetration point is formed in a first region of the first antenna patch in which influence on an electric field generated by the first antenna patch via the first power feed point is minimized.

    Abstract: The present disclosure provides a method and a phase lock detection apparatus for detecting whether a phase of an output signal is locked to the phase of a reference signal. The apparatus includes a first divider that individually frequency-divides first and second pulse signals, a phase frequency detector that outputs third and fourth pulse signals that correspond to a phase difference between the frequency-divided first and second pulse signals, a second divider that individually frequency-divides the third and fourth pulse signals, and a determiner that determines whether a phase of the second pulse signal is locked, based on the frequency-divided third and fourth pulse signals.

    Abstract: Disclosed are a transmitter and method of combining multiple contiguous and non-contiguous frequency bands in a wireless communication system using carrier aggregation. The transmitter includes a first communication unit for converting a first baseband signal into a first RF signal of a first band, a second communication unit for converting a second baseband signal into a second RF signal of a second band, a combiner for outputting a third RF signal by combining the first RF signal and the second RF signal, and an amplifier for amplifying the third RF signal.
