Question 1
Given an RF system with the following parameters: P_TX = 15 dBm, G_TX = 4 dBi, L_TX_cable = 2 dB, distance = 150 m, frequency = 900 MHz, L_misc = 3 dB, G_RX = 2 dBi, L_RX_cable = 1 dB. Calculate P_RX.
💡 Hint: Break every part of the formula down step-by-step.
Question 2
An RF system exhibits a noise figure of 5 dB and operates at room temperature of 290 K. Calculate the noise floor at a bandwidth of 20 MHz.
💡 Hint: This requires converting thermal noise to dBm and considering the noise figure.
