[High-speed Bipolar Power Supply/Power Amplifier Series] Boost Amplifier SG-300
It can be combined with SG-4104/4105, DG-8000, and other signal generators to amplify up to 24Vp-p (at 50Ω) and 48Vp-p (open) outputs.
Features
- High output
When combined with a 48Vp-p (when the output end is open) and 24Vp-p (at 50Ω termination) commercial signal generator, the required voltage in each field can be easily obtained. - External AM modulation input function. Easily achieve PAM modulation
Simply adding a signal to the AM modulation input will add AM modulation to the main signal.
In addition, by using the offset function together, the DC component of the AM (pulse amplitude modulation) signal can be changed very easily. Traditionally, PAM has also been used in refrigerators and washing machines in the consumer electronics field, and further applications are expected in the future. - LO-Ω output mode
50Ω output and LO-Ω output can be switched. By using the LO-Ω output mode, even if current flows to the output load, if it is in the output current range, it is possible to supply a stable signal to the load while maintaining the voltage amplitude. - Broadband 1MHz
A maximum amplitude of 48Vp-p can be maintained while maintaining a band of 1MHz. It is very effective in the mechatronics field.
Application
- Signal source for driving Hall element sensors used in automobiles, etc.
- Power supply for small signal semiconductor devices
- Emulation of small batteries
- Signal source for driving power devices (small motors, positioning motors, etc.)
- Emulation signal for PAM control
PAM waveform generation example
The input of the SG-300 is a PWM signal (CH1) with a 20kHz cycle. Here, if the AM modulation input of the SG-300 is inputted with a 50Hz sine wave and the AM modulation is applied, a PAM signal with a modulation frequency of 50Hz is obtained.
