RF power amplifiers are chosen by the signal level needed at the DUT, not just by headline output power. Frequency range, CW or pulsed operation, gain, input drive, load mismatch protection, harmonics, cooling, and remote control all affect the final bench design.
Current XGY Fit
| Need | Best fit | Why it fits |
|---|---|---|
| High-power broadband drive from 0.7 to 2.7 GHz | XPA-0727-200 RF Power Amplifier | Solid-state amplifier delivering 200 W CW output with at least 53 dB gain and N-type RF connectors. |
| Frequency outside 0.7 to 2.7 GHz | Project quote | Share band, power, duty cycle, and load condition so XGY Tek can recommend the correct amplifier class. |
Selection Factors
| Factor | What to check |
|---|---|
| Frequency range | The amplifier must cover the full signal band, including margins and modulation bandwidth. |
| Output power at the DUT | Include cable loss, coupler loss, chamber path loss, antenna gain, and required field strength. |
| Gain and input drive | Confirm the signal generator can drive the amplifier without overdrive or compression. |
| Protection and duty cycle | Check VSWR protection, over-temperature handling, cooling, and continuous-duty requirements. |
How to Decide
Calculate power at the DUT
Start from the required DUT input power or field strength and work backward through cables, couplers, switches, antennas, and fixtures. The amplifier should provide margin without forcing the source or amplifier into unwanted compression.
Protect the amplifier and the DUT
High-power RF benches should include directional couplers, power monitoring, attenuators where needed, interlocks, and a clear load-mismatch plan. The XPA-0727-200 includes over-VSWR, over-temperature, and over-excitation safeguards, but system protection still matters.
Plan control and cooling
Production and EMC benches often need remote control, status logging, rack airflow, and controlled warm-up. Confirm GPIB or LAN integration, rack space, exhaust path, and operator safety before finalizing the amplifier.
For an RF amplifier quote, share frequency band, required CW or pulsed power, input source level, duty cycle, load type, connector preference, and remote-control requirements. XGY Tek can size the amplifier and monitoring accessories together.
