TDA7021T

Fig.3 Field strength voltage (V9-3) at Rsource = 1 kΩ; f = 96,75 MHz; VP = 3 V.

Fig.4

Mono operation: AF output voltage (Vo) and total harmonic distortion (THD) as functions of input e.m.f.

(EMF); Rsource = 75 Ω; frf = 96 MHz; 0 dB = 90 mV. For S+N and noise curves (1) is with muting enabled

and (2) is with muting disabled; signal

∆f = ± 22,5 kHz and f

m = 1 kHz. For THD curve, ∆f = ± 75 kHz and

fm = 1 kHz.
