Abstract
Disclosed is a frequency multiplication apparatus including a first frequency multiplier receiving a first signal having a first frequency and outputting a second signal having a second frequency by multiplying the first frequency by ‘n’ (‘n’ being a positive integer), a second frequency multiplier receiving the second signal and outputting a third signal having a third frequency by multiplying the second frequency by ‘m’ (‘m’ being a positive integer), and a coupler connected between an output of the first frequency multiplier and an input of the second frequency multiplier and outputting a part of the second signal.
Claims15
A frequency multiplication apparatus, the apparatus comprising:
- a first frequency multiplier configured to receive a first signal having a first frequency and to output a second signal having a second frequency by multiplying the first frequency by ‘n’ (‘n’ being a positive integer);
- a second frequency multiplier configured to receive the second signal and to output a third signal having a third frequency by multiplying the second frequency by ‘m’ (‘m’ being a positive integer);
- and
- a coupler connected between an output of the first frequency multiplier and an input of the second frequency multiplier and configured to output a part of the second signal.
A frequency multiplication method, the method comprising:
- in a first operating mode, receiving an initial signal having an initial frequency;
- in the first operating mode, generating a first signal having a first multiplication frequency by multiplying the initial frequency by ‘n’ (‘n’ being a positive integer);
- in the first operating mode, outputting the first signal to a first external device through a first coupler circuit;
- and
- in the first operating mode, generating a second signal having a second multiplication frequency by multiplying the first multiplication frequency by ‘m’ (‘m’ being a positive integer).
