Ofte stillede spørgsmål
Please tell me what frequency range do you need a 15W power amplifier for? If your needs do not match our inventory, it will take 2~3 weeks to customize.
Okay, tjek venligst her.
Spørgsmål: Can you show OUT +12V IN only?
Svar:
- It would be best to have the technical parameters and specifications of the amplifier written on the casing like we currently have in the above picture.
- One day in the future, when you need to return it to the factory for repair, our engineers can repair or replace it according to the specifications of the shell.
- If there are no these words on the shell, we have no way to provide after-sales technical support.
Spørgsmål: Can you please not print the production date on the casing?
Svar: We provide 12 months quality guarantee. The production date on the casing is an important basis for after-sales service.
- Each PA has a center frequency point. The PA can work normally within a certain frequency range, but its performance is the best at the center frequency point.
- The frequency range of PA is +-15Mhz of the center frequency. If the center frequency point is 600Mhz, then this PA frequency range is 600Mhz, + / -15Mhz, from 585Mhz to 615Mhz.
- The max frequency range is 10% of the center frequency point.
for eksempel, if you choose the working frequency of 500Mhz, then the frequency range is 10% of the frequency, so the frequency range should be 50Mhz, from 475~525Mhz.
-
The current will increase and it will not be damaged, but no load and short circuit for a long time are not recommended.
-
Our Engineers are worried about burning out the filter after the power amplifier. High power for a long time will cause the filter to heat up.
-
The power amplifier has no load and short-circuit protection circuits.
