What is the minimum RF input power for AD8342 to give an clear IF output? Does this specification exist?
If not, based on the condition below, how low the RF input can go?
RF frequency: 1GHz
LO frequency: 1.0001GHz (0dBm)
IF frequency: 100KHz
Will there be any new part which is similar AD8342 and with better noise figure? (RF input - 0MHz to 2GHz)
The RF input of ad8342 accepts input signals as large as 1.6 V peak-to-peak or 8dBm (relative to 50 Ω) at P1dB. There is no typical value for the lowest input signal level. It highly depends on ambience noise and how good SNR is desired. If noise figure is concerned and application frequency range is from 400MHz -1.2GHz, you could give ad8344 a shot.
