초록

A double-balanced frequency up-converter using the Gilbert cell structure has been designed with the TSMC $0.18\;{\mu}m$ CMOS library. The frequency up-converter consists of a Mixer core and IF / LO balun. Frequency Up-converter exhibits a 3.4 dB conversion gain with a - 7.6 dBm $P_{1dB}$ for IF power of -10 dBm and LO power of 0 dBm inputs. It also exhibits 92.2 % modulation depth as a ASK modulator.
