And 2 attenuators are used to obtain a good noise performance and high linearity property. The designed CMOS LNA/mixer have achieved the control of gain with 3 dB step, input second order intercept point (IIP2) of 1.37 dBm and input third order intercept point (IIP3) of -3.6 dBm at high gain low frequency mode. Moreover, a noise figure of 6.4 dB has been achieved at the frequency range from 950-2150 MHz. The LNA circuit consumes a total current of 25 mA together with the supply voltage of 1.8 V and the chip area of LNA and mixer are 0.8x0.53 and 0.8x0.6 mm, respectively.} }
