Common Emitter Large Signal Parameters
Linear output voltage Vo = f (IC)
VCE = 8 V, dIM = 60 dB, f1 = 806 MHz,
f2 = 810 MHz, ZS = ZL = 50 Ω
Note:
The transistor is driven by 2 adjacent signals f1, f2 with equal output power levels Po for each
carrier.
The distance dIM between Po and the third order intermodulation products PIM
(2f1 – f2 or 2f2 – f1) is:
dIM = Po – PIM
where Po = 10 log (V o2 / (50 Ω · 1 mW)) (dBm)
and Vo = linear output voltage of each carrier.
The 3rd order intercept point IP3 will be found by extrapolation to the point where PIM would be
identical to Po:
IP3 (output) = Po + dIM/2.
Linear output voltages for other dIM (e.g. 50 dB) can be calculated thereby.
