Detailed Solution
Download Solution PDFConcept:
The gain in dB is defined as:
Power in dBm is expressed as:
P = Power to be expressed in dBm
Calculation:
Given
Pin = 1 μW
P(dB) = 30 dB
Putting these values in the above equation, we get:
Taking Antilog on both sides, we get:
Pout = 1 mW
Convert output power to dBm
P(dBm) = 10log10(1)
P(dBm) = 0 dB
