6. Consider the wireless local area network receiver front-end shown below, where the bandwidth of the bandpass filter is 150 MHz, centered at 2.4 GHz. If the system is at 290K, find the noise figure of the overall system. What is the output SNR if the input signal level is -85 dBm? Can the components be re- arranged to yield a better noise figure? 5+5+5=15 L=1.5dB G=10dB f = 2dB G=15dB f=2 dB Figure 3: Figure for problem 6.
