Coaxial x4 Multiplier up to 44 GHz

Coaxial x4 Multiplier 18–44 GHz from AT Microwave

The AT-AM4-1844-18L is a broadband active frequency multiplier that converts low-frequency RF signals into the millimeter-wave spectrum with high efficiency and spectral purity. Designed for demanding applications in 5G infrastructure, radar systems, test equipment, and SATCOM, the device delivers consistent +18 dBm output power across its entire 18–44 GHz operating range. The x4 multiplication factor translates input signals from 4.5–11 GHz directly into the mmWave domain.

Technical Specifications

  • Frequency Conversion: Input 4.5–11 GHz, multiplication factor x4, output 18–44 GHz
  • Output Power: +18 dBm typical across full bandwidth
  • Harmonic Rejection: Greater than 15 dBc suppression of unwanted x3 and x5 harmonics
  • Maximum Input Power: +15 dBm
  • Connectors: SMA Female (input), 2.92 mm Female (output)
  • Power Supply: +5 V to +8 V DC, 280 mA typical current draw
  • Operating Temperature: −45°C to +85°C
  • Housing: Gold-plated copper, 80 g weight

Applications

  • 5G & 6G Telecommunications: Direct signal generation for 28 GHz and 39 GHz frequency bands
  • Millimeter-Wave Radar: Automotive and industrial sensing systems requiring clean, stable local oscillator signals
  • Test & Measurement: Vector network analyzer and spectrum analyzer stimulus sources covering sub-mmWave and low-mmWave bands
  • SATCOM & Defense: Secure communication and electronic warfare applications requiring broadband mmWave generation

The AT-AM4-1844-18L integrates input and output buffer stages that stabilize gain across load variations while minimizing drive-level sensitivity. Harmonic suppression exceeding 15 dBc ensures compliance with spectral masks in regulated frequency bands and reduces intermodulation distortion in cascaded RF chains.
