Wideband Power Amplifier [HF-A series]  
Wideband Power Amplifier


Q: What is the frequency range of your wideband power amplifiers?

A: Our wideband power amplifiers can cover infrasonic (IF), audio (AF), ultrasonic (UF), and part of the radio frequency (RF) ranges, from 5 Hz to 600K Hz and up to 800K Hz for reduced power.


Q: What is the standard output voltage range?

A: The standard output voltage, without output transformer, is 0 - 28 V rms.


Q: What is the standard output power range?

A: The output power rating ranges from 50 watts to 1400 watts when used as an individual unit.


Q: What if I need a higher output voltage?

A: With external output transformers, the output voltage can go up to a maximum of 10K V rms.


Q: What if I need a higher power?

A: Multiple wideband power amplifier units can be combined for a higher output power. Contact sales or technical support for more information.


Q: How do I know which model I need?
