Q.9. For a single balanced mixer circuit in Figure-3.1, RF input frequency is 1100 MHz and LO frequency is 700 MHz. Consider the harmonics in the square wave LO signal up-to the fifth-order term as shown in Eqn- 3.1. 4. 1 1 ))=) Eqn-3.1 3 5 120 = sin(@zol ) + sin (30/01) + sin (50,01) ) = LO NT (a) what are the various frequencies which will be generated at the output 11? [6 marks] (b) If lo is a unit amplitude RF signal. Calculate the power-conversion gain of this mixer. Take Vlo to be a square wave represented by Eqn-3.1. MOSFETs M1 and M2 are assumed to be ideal switches. Output is taken at 11. [6 marks] Q.9.
