“…The up-conversion mixer [10,11,12,13,14,15] which is an important component of a wireless transceiver modulates IF signal onto RF frequency. It is hard to design a mixer which can accomplish broadband output along with low power dissipation, low noise figure and high linearity [16,17,18].…”

A 45 MHz-2.5 GHz broadband CMOS up-conversion mixer implemented in a conventional 0.18 μm 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 0.3-20.15 MHz frequency range. The up-conversion mixer draws 3 mA current from a 1.8 V supply voltage, and the core chip dimension of the mixer is 0.05*0.08 mm 2 . At the frequency range of 45 MHz-2.5 GHz, the output third-order intercept point (OIP3) is larger than 9 dBm, the LO-RF isolation characteristic of the mixer is less than -60 dB, and the maximum conversion gain is 5.21 dB. The mixer achieves a minimum noise figure of 8.42 dB.
