Mixer Conversion Loss and Isolation Given the system shown in Figure 8-63 and the following mixer specifications:

• CLdB = 10 dB

• RF:IF isolation = 17 dB

• LO:IF isolation = 22 dB

• LO:RF isolation = 25 dB

• 2 × LO power is 25 dB below the desired output

• 2 × RF power is 28 dB below the carrier

find the power level, frequency, and nature (e.g., is the signal an LO+RF, 2LO-RF) of each signal present on the IF port of the mixer.

Notes: The signal powers shown in Figure 8-63 are accurately drawn with respect to frequency but not to power level. In other words, don’t make any assumptions about the power in each signal from the drawing. In the cases where you do not have enough information to find the power level of a signal, simply state that fact.
