Abstract

A dual‐band RF front end for the DVB‐H direct conversion receiver is implemented using 0.18‐μm CMOS technology. To achieve the low‐NF and high‐IIP3 performance, the LO stage of the passive mixer is optimized with respect to the transistor size and gate bias. The measured results show that the NF is below 4.8 dB and the IIP3 at low‐noise amplifier off state is above +3.5 dBm all over the bands. The chip size is 0.75 mm^2^ excluding pads and the current consumption is 5.6 and 6 mA at 1.8 V supply, respectively. © 2011 Wiley Periodicals, Inc.
