(a) Please evaluate the noise figure (1.5%) and the gain (1.5%) in dB of the system shown below. (b) If a Bluetooth signal with 2-MHz bandwidth and -100-dBm power input to this system, please evaluate signal-to-noise ratio (SNR) in dB of the signal at the output port in the room temperature 300°K. [Hint: the noise with a bandwidth (B) in a given temperature (T) is KTB, in which K is the Boltzmann constant 1.380649 × 10-23 J/K ] (3%) = LNA1: LNA2: LNA3: Gain = 15 dB Gain 10 dB Gain 10 dB NF = 3 dB NF = 5 dB NF Attenuator: Loss = 2 dB m Output Input 5 dB
