A 30-512 MHz GaN RF power amplifier is a practical choice when a VHF/UHF project needs one broadband solid-state amplifier across a wide operating range instead of a set of narrow modules. CorelixRF’s local CRF-PA-30M512M datasheets identify the family as a third-generation GaN SSPA platform for broadband RF system amplification, SDR / OFDM signal amplification, RF test and measurement, and system-level RF integration.
The specification-backed model set includes 30W, 50W, 100W, 150W, and 200W CW output classes. All five models cover 30 MHz to 512 MHz, use a nominal 28 V DC supply range of 24 V to 32 V, and specify 200 MHz instantaneous bandwidth for broadband or OFDM-type signals. That makes the series relevant to engineers who need wide VHF/UHF coverage, but it also means the RFQ should include signal type, duty cycle, bandwidth, cooling, and control requirements.
| Model | Rated CW output | Psat minimum | Small-signal gain | Current typ/max | Connector and package |
|---|---|---|---|---|---|
| CRF-PA-30M512M-30W | 30 W | 25 W | 36-46 dB | 3.2 / 4 A | SMA-KFD46, 125 x 59 x 21.5 mm |
| CRF-PA-30M512M-50W | 50 W | 40 W | 38-48 dB | 7.2 / 9 A | SMA-KFD46, 125 x 59 x 21.5 mm |
| CRF-PA-30M512M-100W | 100 W | 80 W | 41-51 dB | 14.5 / 18 A | SMA-F in / N-F out, 160 x 120 x 25 mm |
| CRF-PA-30M512M-150W | 150 W | 120 W | 43-53 dB | 16 / 20 A | SMA-F in / N-F out, 200 x 158 x 25 mm |
| CRF-PA-30M512M-200W | 200 W | 158 W | 44-54 dB | 29 / 36 A | SMA-F in / N-F out, 200 x 158 x 25 mm |
What Changed From a Generic Selection Guide
This version is based on the local datasheets, not only public product-page assumptions. The lower-power 30W and 50W modules use a D-Sub 9-pin control connector and compact 125 x 59 x 21.5 mm mechanical format. The 100W, 150W, and 200W versions move to D-Sub 15-pin control, pull-core capacitance power input, and SMA-F input / N-F output RF interfaces. That distinction matters for OEM wiring, cable routing, and thermal design.
The datasheets also list gain flatness of -4 to +4 dB, input VSWR maximum 1.8, spurious level of -60 dBc, and harmonic reference of -10 dBc for the covered models. These are useful starting points for bench planning, but final acceptance should still be tied to the production test data supplied for the ordered configuration.
Control, Protection, and Cooling Notes
The 30W and 50W versions include PA enable through D-Sub 9-pin logic, fast 10 us enable/disable behavior, external heat-sink cooling, and over-temperature shutdown above 80 C +/- 5 C with recovery below 70 C +/- 5 C. The 100W to 200W versions add optional RS485 monitoring/control, gain adjustment, analog temperature reporting, forward/reverse power monitoring, alarm output, hardware reset support, and lockout behavior for over-VSWR, over-voltage, and over-current conditions.
For a custom RF amplifier review, state whether the amplifier will be used as a module, integrated into a larger RF front-end platform, or paired with an SDR source. Include the instantaneous bandwidth requirement if the signal is OFDM, wideband modulation, or frequency agile.
Application Fit
This family is strongest when the buyer needs wide 30-512 MHz coverage with a defined CW output class and a clear integration path. The 30W and 50W models are easier to fit in compact test benches. The 100W model is a mid-power option with SMA-F / N-F interfaces and higher current demand. The 150W and 200W units need more careful power-supply and heat-sink review.
For RF testing and validation , the right model is the one that can deliver the required output at the amplifier port after cable loss, test fixture loss, and load condition are considered. For SDR or OFDM use, do not specify only frequency and watts; include waveform bandwidth, peak-to-average behavior, and duty cycle.
FAQ
Which CRF-PA-30M512M models are covered by local datasheets?
The local specification set covers 30W, 50W, 100W, 150W, and 200W versions across 30 MHz to 512 MHz.
What semiconductor technology is stated?
The datasheets describe the family as a third-generation GaN solid-state RF power amplifier platform.
What instantaneous bandwidth is stated?
The datasheets specify up to 200 MHz instantaneous bandwidth for broadband / OFDM-type signal amplification.
Are the control connectors the same for every power class?
No. The 30W and 50W models use D-Sub 9-pin control, while 100W, 150W, and 200W versions use D-Sub 15-pin control with additional optional monitoring functions.
What should be included in the RFQ?
Provide frequency range, output power, signal type, instantaneous bandwidth, control interface, mechanical constraints, cooling method, and environmental requirements.
