FAQ
Q1: What frequency ranges does this RF power amplifier support?
The module supports two specified frequency ranges: 20–88MHz and 114–500MHz. These are separate frequency ranges, not continuous coverage from 20MHz to 500MHz.
Q2: Is the module available in both 40W and 60W versions?
Yes. The module is available in 40W and 60W transmit output power configurations. Please specify your required output power when requesting a quotation.
Q3: What is the TX/RX switching time?
The specified TX/RX switching time is ≤1μs. Actual system performance depends on the control sequence, operating conditions, and integration requirements.
Q4: What power supply does the module require?
The specified DC supply voltage is 24–28V. Confirm the actual current requirements for your selected configuration with the engineering team before selecting a power supply.
