Notes to the characteristics

1. Input frequency = 1 MHz, output frequency = 468 kHz;

SC = V-V----io--(--(R--I-FF---))- × -N----2----R-⁄---N----3-- ( see TR2 Component data)

Where R = 1.2 kΩ (total impedance at pin 16).

2. α = 20 log (Vi at fi = 468 kHz)/(Vi at fi = 1 MHz); Vo = 10 mV; no AGC.

3. Input frequency = 468 kHz; m = 30% modulated with fmod = 1 kHz; Rsource = 800 Ω unless

otherwise specified.

4. Front-end connected to IF plus detector part (see Fig.5). Input frequency = 1 MHz; m = 80%

modulated with fmod = 1 kHz.

5. Input frequency = 100 MHz, output frequency = 10.7 MHz;

Sc = V-V----io--(--(R--I-FF---))- × -N----1----R-⁄---N-----2- (see TR3 Component data)

Where R = 6.6 kΩ (total impedance at pin 2).

6. Input frequency = 10.7 MHz; frequency deviation, ∆f = 22.5 kHz and fmod =1 kHz; unless

otherwise specified.

7. Reference: AF output voltage = 0 dB at Vi(IF) = 1 mV;

No mute: V1 = V8;

With mute: V1 = 0 V.

8. AM suppression is measured with AM only: m = 0.8% and fmod = 1 kHz referred to AF output at

FM only: ∆f = 75 kHz and fmod = 1 kHz.

9. Value to be fixed.
