In this study, a broadband low noise amplifier (LNA)/mixer for digital video broadcasting‐satellite receiver tuner was fabricated by a 0.18‐µm complementary metal oxide semiconductor (CMOS) process. The proposed broadband LNA receives positive feedback and incorporates a single‐ended differential converter to mixer. Two attenuators are used to obtain good noise performance and high linearity. Moreover, the designed CMOS LNA/mixer achieved gain controls in 3‐dB steps, an input second‐order intercept of 1.37 dBm, and an input third‐order intercept of −3.6 dBm in high‐gain low‐frequency mode. The 6.4‐dB noise of LNA was achieved in the frequency range of 950–2150 MHz. The circuit consumes a total current of 25 mA at a supply voltage of 1.8 V and the chip area of the LNA and the mixer are 0.8 × 0.53 mm 2 and 0.8 × 0.6 mm 2 , respectively. © 2015 Wiley Periodicals, Inc.
