Transmitter mode
This amplifier can generate a significant
amount of power at frequencies used for
radio transmission and reception. The
amplifier should not be used for
telecommunication as described in the
R&TTE directive 95/5/EC. Also for this
reason always use coaxial cables.
Amplifier characteristics
In the following pages, several amplifier
characteristics are illustrated:
- Frequency response as a function of
capacitive load (Fig. 5, 6)
- Rms output noise voltage versus
capacitive load (Fig. 7)
- Noise and offset with and without
capacitive load box (Fig. 8)
- Sine and triangle wave responses (Fig.
10, 11)
- Square wave response (Fig. 12, 13, 14)
- Step response (Fig. 14)
- Capacitive load dependency of square
wave output (Fig. 15)
