25–520 MHz, 100 W model overview
This module is specified for 25–520 MHz, with CW output of at least 50 dBm (100 W) and customized gain of at least 48 dB. The table lists gain flatness of ≤2±1 dB, input VSWR of ≤1.6, input power of 0±2 dBm and maximum input of +6 dBm.
RF connectors and electrical integration
The listed RF input is SMA-F and the RF output is N-K. These are different connector types, so confirm the mating cables and system interface before ordering. The working-voltage range is +28 V to +32 V, with operating current listed as ≤9–12.5 A. The table also gives a 28 V/15 A supply reference; confirm the appropriate supply capacity for the exact configuration.
The PTT port is listed as default off, with 3.3–5 V for on. Other published details include over-temperature protection above 80°C, open-circuit protection, spurious output of ≤−65 dBc, a worst-point harmonic specification of ≤−10 dBc and an operating-temperature range of −30°C to +55°C. The stated dimensions are ≤181 × 79.2 × 26.2 mm without connectors, and a radiator is specified for power-amplifier testing.
Selection and installation checklist
- Confirm the required band is fully within 25–520 MHz.
- Verify CW output, customized gain and gain-flatness requirements.
- Check the SMA-F input and N-K output connector assignments.
- Confirm DC supply capacity, PTT logic and protection requirements.
- Review mounting, radiator installation and operating-temperature limits.
Frequently asked questions
What is the difference between the RF input and output connectors?
The product table specifies SMA-F for RF input and N-K for RF output. Use the manufacturer’s drawing to verify the port locations and mating interfaces.
Does 50 dBm correspond to 100 W?
Yes. 50 dBm is equivalent to 100 W. The listing labels the value as CW output; confirm the test conditions and guaranteed performance in the current datasheet.
For more guidance, read the 100 W RF PA selection guide and thermal design guide. Browse the RF power amplifier module category or contact QHXK for current documentation.
