Mixer is a kind of circuit in which two signals are ‘mixed’ to produce desired difference or sum frequencies, which is employed for a wireless communication system to down/upconvert the input signal to a much lower / higher carrier frequency than the input RF signal. To enrich the background knowledge, a comprehensive fundamental of mixer will be firstly presented in sections 1 and 2. General design considerations will be then described. Several configurations of mixer circuits will be addressed in section 4. To summarize the chapter, a case study concerned with a 5.26-GHz CMOS up-conversion mixer for IEEE 802.11a WLAN will be described in the final section
