The 2-6 GHz GaN RF power amplifier range is often used when an SDR chain, microwave test bench, or broadband RF system needs meaningful output power across S-band and adjacent microwave frequencies. CorelixRF’s local CRF-PA-2000M6000M datasheets identify the 30W to 200W models as third-generation GaN SSPA modules designed for broadband RF amplification, SDR / OFDM signal amplification, RF test and measurement, and system-level integration.
The local datasheets confirm 2000 MHz to 6000 MHz operating coverage, up to 200 MHz instantaneous bandwidth, +28 V nominal supply, external heat-sink cooling, and different control/interface options depending on power class. This matters because SDR and OFDM projects are not defined by frequency and watts alone; waveform bandwidth, drive level, peak-to-average behavior, and duty cycle can decide whether a model is suitable.

RF Performance Details From the Datasheets
The 30W to 200W module datasheets list gain flatness of -3 to +3 dB, input VSWR maximum 1.8, spurious level of -60 dBc, and harmonic reference of -10 dBc. These values are useful for RF testing and validation planning because they help estimate leveling, source drive, and expected output variation across the operating band.
The 30W model uses D-Sub 9-pin control with PA enable logic and fast 1 us enable/disable behavior. The 50W and higher modules use D-Sub 15-pin control plus pull-core capacitance power input, and the datasheets describe optional RS485 monitoring/control, analog temperature/current reporting, alarm output, hardware reset, gain adjustment, and power adjustment where applicable.
SDR and OFDM Integration Notes
For SDR amplifier integration, the key question is whether the SDR source can drive the selected amplifier across the entire 2-6 GHz band. The datasheets identify the family for SDR / OFDM-type signal amplification and 200 MHz instantaneous bandwidth, so buyers should provide waveform bandwidth, modulation type, source output power, duty cycle, and whether the amplifier will be used in continuous or test-sequence operation.
The 30W version is a compact starting point for lower-power experiments. The 50W, 100W, 150W, and 200W modules need more careful review of supply current, heat-sink capacity, cable loss, and downstream load. If the amplifier will feed an antenna path or a non-ideal load, reflected power and VSWR handling should be discussed before quotation.
Practical RFQ Inputs
A complete RFQ should include frequency range, required output at the amplifier port, source drive across frequency, waveform, instantaneous bandwidth, duty cycle, load condition, cooling design, connector preference, control interface, and whether test data or mechanical drawings are needed.
