Amplifier Research 1000LA RF Amplifier Repair and Calibration
The Amplifier Research 1000LA is a solid-state broadband linear RF power amplifier — a 1000 W-class “LA” amplifier covering a wide RF band for EMC immunity testing and high-power RF applications. As a high-power RF amplifier, its faults concentrate in the RF output stage, 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 1000LA for EMC test labs and RF engineering teams.
Common AR 1000LA problems we fix
- Low or no RF output / partial power — output-module or combiner failure on a high-power amp, isolated and repaired so it delivers rated power.
- Gain flatness off — gain drift across the band, recalibrated.
- Fault/shutdown or overheating — power-supply, protection, or cooling faults, repaired.
- Output modules unbalanced — one path down while others work, repaired.
- Control or interface faults.
FAQs
My 1000LA only makes partial power — fixable? Yes. That usually means one output module or combiner path is down; we isolate and repair it so full rated power is restored across the 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.
