Introducing the AT-AM4-1844-18L: A High-Performance x4 Frequency Multiplier by AT Microwave

If you’re looking for a broadband, compact, and high-output frequency multiplier for millimeter-wave applications, the AT-AM4-1844-18L x4 Active Multiplier from AT Microwave is a standout choice. Designed for performance, versatility, and reliability, this device is ideal for engineers working in 5G communication, radar systems, test and measurement, and RF-over-Fiber (ROF) systems.

Key Features

  • Input Frequency: 4.5 – 11 GHz

  • Output Frequency: 18 – 44 GHz

  • Multiplier Factor: x4

  • Output Power: +18 dBm (typical)

  • Low Harmonic Content: >15 dBc suppression for x3 and x5 harmonics

  • Compact and Lightweight: 80g, gold-plated copper housing

  • Input Connector: SMA Female

  • Output Connector: 2.92mm Female

Performance That Delivers

The AT-AM4-1844-18L is engineered for broadband performance, delivering high output power with only a low-level input drive. It operates effectively across a wide output frequency range of 18 GHz to 44 GHz, with a consistent output power of +18 dBm typical. The integrated input and output buffers enhance gain and reduce sensitivity to source/load variations.

Its excellent harmonic suppression—greater than 15 dBc for unwanted x3 and x5 harmonics—ensures clean spectral performance, making it a dependable multiplier in RF systems where signal purity is critical.

Ideal for Modern RF Applications

This x4 multiplier is particularly well-suited for cutting-edge applications, including:

  • 5G Infrastructure (28/39 GHz bands)

  • Radar Systems and Sensing

  • High-Frequency Test Equipment

  • RF-over-Fiber (ROF) Transmission Systems

Whether you’re working on lab setups or integrating into advanced telecom systems, the AT-AM4-1844-18L offers the bandwidth, power, and stability your system needs.
