Signal path of a GSM radio receiver is composed of an antenna followed by a BPF, LNA, BPF, Mixer, IF BPF and IF amplifier. If the noise temperature of the antenna is 400K and the noise figure of the LNA, mixer and IF amplifier are 5, 6 and 10dB, respectively and their IIP3s are 15, 10 and 30dBm. Assuming that the gain of LNA and IF amplifier are 13 and 40dB, while mixer has a loss of 6dB and each one of the BPFs cause a loss of 3dB. A) Draw the signal path of the receiver. B) Find the Overall noise figure, gain and IIP3 of the receiver. C) Find the minimum detectable signal assuming that the bandwidth of the input signal is 50 KHz, minimum SNR is 12dB and the reference impedance is 50ohm. D) For the three cases that Si = -90, -30, 0 dBm find the output signal power (hint: check and make sure that none of the stages will saturate), draw a figure showing the power of the signal after each one of the stages and the output SNR. E) Find the SFDR of the receiver.
