Description

Amplifier Research 400A400 RF Amplifier Repair and Calibration

The Amplifier Research 400A400 is a solid-state broadband RF power amplifier — 400 W covering roughly 10 kHz–400 MHz (the “A” denotes a wideband class), an EMC immunity amplifier with wide frequency coverage. As a high-power solid-state RF amplifier, its faults concentrate in the RF output stages and combiners, the high-power supply, and thermal management — not the low-voltage power-supply faults its category label implies.

June Company repairs and calibrates the AR 400A400 for EMC test labs and RF engineering teams.

Common AR 400A400 problems we fix

Control-interface faults — the control/monitoring electronics not responding correctly, repaired.
Low or no RF output — output-stage failure, repaired so it delivers rated power across the wide band.
Partial power / one module down — a failed output path on a high-power amp, isolated and repaired.
Fault/shutdown or overheating — power-supply, protection, or cooling faults, repaired.
Gain flatness off — gain drift across the band, recalibrated.

FAQs

My 400A400 output is down or partial — repairable? Yes. RF output-stage faults are the usual cause and they’re repairable, then verified so it delivers rated power and gain across the wide band, with a NIST-traceable certificate.

Is gain flatness verified? Yes — checked across the band against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
