What is the equivalent noise temperature of the source over


A cellular telephone receiver front-end circuit is shown below. The operating frequency is 1805- 1880 MHz, and the physical temperature of the system is 300 K. A noise source with Ni = -95 dBm is applied to the receiver input. 6

(a) What is the equivalent noise temperature of the source over the operating bandwidth?

(b) What is the noise figure (in dB) of the amplifier?

(c) What is the noise figure (in dB) of the cascaded transmission line and amplifier?

(d) What is the total noise power output (in dBm) of the receiver over the operating bandwidth?
