Hello,
for the RF-Test of modern Transceiver Chips (Bluetooth, GPS, WLAN, etc.) the minimal receive power is specified as -145dBm (for example).
Isnt it unrealistic to establish such low sinusoidal signals.
I am thinking about our test equipment, and I cant believe that -145dBm is still above the noise floor.
-145dBm = 3.16 E-15 mW = 3.16 E-18 W = 12.5 nVRMS for 50 Ohm sytem.
Thank you for any comments.
