The RF amplifier of a receiver has an input resistance of 1000 Q, and equivalent shot noise resistance of 2000 Q, a gain of 25, and a load resistance of 125 kQ. Given that the bandwidth is 1.0 MHz and the temperature is 20°C, calculate the equivalent noise voltage at the input to this RF amplifier. If this receiver is connected to an antenna with an impedance of 75 Q, calculate the noise figure.
