VBA 200 Series — 12 to 200 MHz Class-A RF Power Amplifiers

VBA200-3000 RF Power Amplifier

12 MHz – 200 MHz | 3000 W | Class-A | 100 % Mismatch Tolerant

 

The Vectawave VBA200-3000 is a high-power, broadband RF amplifier engineered for the most demanding electromagnetic compatibility (EMC) immunity tests and high-power RF applications. Designed to deliver 3000 W of rated power across 12 MHz to 200 MHz, this amplifier combines rugged Class-A MOSFET push-pull output stages with Vectawave’s proprietary power combining architecture to optimize efficiency, linearity, and mismatch tolerance.

Key Technical Advantages

    • 3000 W broadband output for conducted and radiated immunity tests

    • Class-A operation for very low distortion and predictable linear performance

    • 100 % mismatch tolerant (Infinity:1 VSWR) — no fold-back or shutdown required

    • Rugged push-pull MOSFET output stages minimize harmonic content

    • High-efficiency proprietary power combiner reduces internal losses

    • Front-panel and remote control via Ethernet, USB, and GPIB

    • Comprehensive monitoring of forward/reflected power and supply health

    • Unconditional stability across the entire frequency band

Why Absolute EMC

Absolute EMC provides application-specific system design (BCI loops, clamps, CDN selection, power meters/couplers, LISNs), installation, and correlation guidance to IEC, ISO, SAE, DO-160, and MIL standards—so your amplifier integrates correctly with sensors, control, and calibration chains from day one.

What to Specify (Selection Guide)

  1. Required test method & level (e.g., IEC 61000-4-6 level X, ISO 11452-4 forward power for clamp Y).

  2. Fixture/transducer type and insertion loss.

  3. Required linear output (P1dB) at the highest frequency of interest.

  4. Available mains power and control interface needs (USB/GPIB).

  5. Space/rack constraints and RF connectorization.
