【 摘 要 】

A 45MHz-2.5GHz broadband CMOS up-conversion mixer implemented in a conventional 0.18µm CMOS technology is presented in this letter. The offered mixer employs a bisymmetric class-AB input stage in order to provide a high linearity and match the IF input impedance over a 0.3-20.15MHz frequency range. The up-conversion mixer draws 3mA current from a 1.8V supply voltage, and the core chip dimension of the mixer is 0.05*0.08mm2. At the frequency range of 45MHz-2.5GHz, the output third-order intercept point (OIP3) is larger than 9dBm, the LO-RF isolation characteristic of the mixer is less than -60dB, and the maximum conversion gain is 5.21dB. The mixer achieves a minimum noise figure of 8.42dB.
