This article describes a RF front end for DVB‐SH (2.17–2.2 GHz) implemented in UMC CMOS 90 nm process. This receiver includes a low noise amplifier (LNA), a single‐to‐differential converter, and a mixer. The LNA is based on cascode topology combined with a narrow band impedance matching and LC tank load. The single‐to‐differential converter generates a pair of differential output signals from a single input, which have balanced amplitude and phase. This converter is followed by a Gilbert cell based quadrature mixer. The measurements show a conversion gain of 15.7–15.5 dB, an input return loss (S 11 ) of −12 dB, and an output compression point of 1.92 dBm. This receiver has a simulated noise figure of 2.2 dB. This combination draws 22 mW from a 1.2‐V supply. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:1944–1949, 2012; View this article online at wileyonlinelibrary.com.
