VBA0860 Series — 0.8 to 6 GHz Class-A RF Power Amplifiers

Broadband, mismatch-tolerant RF power for radiated immunity, stripline, and antenna drive
Vectawave’s VBA0860 Series covers 0.8–6 GHz with true Class-A linearity based on GaN wideband output stages and Vectawave’s quadrature-hybrid combiners. The result is low distortion, high reliability, and unconditional operation into severe mismatch—ideal for IEC/EN 61000-4-3 radiated immunity (stripline/small antennas), DO-160 §20 work, and demanding chamber applications.

 

Key Technical Advantages

  • Class-A architecture for the lowest distortion in EMC immunity; designed to maintain output without fold-back under high reflection.
  • GaN push-pull wideband stages with proprietary quadrature-hybrid combining for efficient, rugged output over 0.8 - 6 GHz. 
  • 0.8 - 6 GHz instantaneous bandwidth for stripline, small antenna drive, and chamber field generation. 
  • Unconditional stability & ∞:1 output VSWR tolerance (any phase) on series models, supporting variable fixtures/antennas.
  • Modern remote interfaces (Ethernet/USB/GPIB) with front-panel control for enable/monitoring/interlocks.

EMC Applications & Standards Coverage

  • Radiated RF Immunity: IEC/EN 61000-4-3 (stripline/small antennas, chamber drive). 
  • Automotive testing for ASLE and Reverb
  • Avionics Susceptibility: RTCA/DO-160 §20 (radiated/conducted—upper-band amplifier drive).
  • General EMC/chamber use: field generation, transducer/fixture drive over 1–6 GHz.

 

Control, Monitoring & Protection (Model-Dependent)

  • Local front-panel control with Ethernet/USB/GPIB remote interfaces for enable, metering, and interlocks. 
  • Designed for continuous duty into high VSWR loads; unconditional stability specified on models like VBA2060-60

Why Absolute EMC

Absolute EMC sizes amplifiers to your field targets and integrates directional couplers/power meters, striplines/antennas, safety interlocks, and monitoring—so your system hits levels with margin from 2 GHz to 6 GHz on day one.

What to Specify (Selection Guide)

  1. Test method & field level (e.g., IEC 61000-4-3 10/20/30 V/m; DO-160 §20).

  2. Fixture/antenna & insertion loss (stripline, log-periodic, biconical, horn).

  3. Required linear output (P1 dB) at 2 GHz and 6 GHz with margin.

  4. Mains power & remote interface needs (Ethernet/USB/GPIB).

  5. Rack space & connectorization preferences.

 

Typical System Block

Signal source / RF generator → leveling & power meter/coupler → VBA2060 amplifier → stripline/antenna → EUT, with reverse-power/VSWR monitoring and interlocks. ∞:1 VSWR tolerance & unconditional stability simplify integration with variable antennas/fixtures.

 

Frequently Asked Questions

Q1. Will the amplifier tolerate severe mismatch from my antenna or stripline?
Yes. VBA 2060 models are designed for EMC with Class-A operation and ∞:1 VSWR tolerance; VBA2060-60 explicitly specifies unconditional stability and ∞:1 any phase. 

Q2. Should I size to rated (P3 dB) or linear (P1 dB) power?
For immunity targets, size to P1 dB at 6 GHz with fixture/antenna loss margin; use rated power only for headline comparison. (See model datasheets for curves.) 

Q3. Can I remote-control these amplifiers?
Yes—Ethernet/USB/GPIB interfaces are provided for enable, metering, and health/interlocks.
