Abstract: Provided is an apparatus. The apparatus includes an input terminal configured to receive an input signal including at least one carrier, a first amplifier stage electrically connected to the input terminal, enabled in a first mode to output a first output signal by amplifying the input signal, and disabled in a second mode, and a second amplifier stage electrically connected to the input terminal, enabled in the second mode to output second and third output signals by amplifying the input signal, and disabled in the first mode.

Abstract: A local oscillator generator (LO generator) may be configured to transmit an LO signal to a mixer. The LO generator may include an input buffer configured to generate a first internal oscillator signal based on the input oscillator signal. The LO generator may include a frequency dividing circuit configured to generate a second internal oscillator signal based on dividing a frequency of the first internal oscillator signal. The LO generator may include an output buffer configured to generate the LO signal based on the second internal oscillator signal. The input buffer and the frequency dividing circuit may each be configured to receive a power voltage independently of the output buffer.
