Consider the wireless local area network (WLAN) receiver front-end shown below, where the bandwidth of the band pass filter is 100 MHz centered at 2.4 GHz. If the system is at room temperature, find the noise figure of the overall system. What is the resulting signal-to-noise ratio at the output if the input signal power level is -90 dBm? Can the components be rearranged to give a better noise figure?
