WebbAbstract: This paper proposes a second-order input-referred intercept point (IIP2)-enhanced 25% duty-cycle local oscillator (LO) quadrature passive mixer configuration with developing a wideband radio frequency (RF) receiver front-end, suitable for 4G and 5G new radio (NR) sub-6 GHz applications. The second order intercept point (IP2) of a direct conversion receiver system is a critical performance parameter. It is a measure of second order non-linearity and helps quantify the receiver’s susceptibility to single- and 2-tone interfering signals. Let’s examine how this nonlinearity affects sensitivity. We can … Visa mer A direct conversion receiver architecture offers several advantages over the traditional superheterodyne. It eases the requirements for RF … Visa mer The third order intercept point (IP3) has an effect upon the baseband signal when two properly spaced channels or signals enter the nonlinear element. Refer back to the transfer function: y(t) = x(t) + a2x2(t) + a3x3(t) + …, where x(t) … Visa mer The calculations given here using the LT5575 I/Q demodulator show that a WCDMA wide area basestation receiver can be successfully implemented using a direct conversion … Visa mer
