AOTF RF drivers

AOTF RF drivers

ERZIA designs and manufactures RF Drivers for space based AOTF and AOM. The limited energy available in space platforms, along with the demanding requirements of reliability, RF output power and linearity requires a dedicated and specific approach to the design and implementation of these modules. ERZIA has several design approaches that allow a fast and efficient implementation of these modules for space applications, which can include not only the RF amplifier, but also additional features like housekeeping signals, variable gain or special impedance matching.

Our AOTF RF drivers

  • Wide range of frequency configurations, from 15 to 500 MHz
  • Optimized output power: 0.25 W, 0.5 W, 1 W, 2 W, 3 W
  • Maximum output power up to 10 W
  • Optimized DC power consumption
  • Optimized harmonic rejection, even for multi-octave bandwidth

Customizing for you

  • Use some of our models “as is” or ask for your specific AOTF requirements
  • Complete customization of RF Drivers
  • On demand housekeeping signals
  • On demand Telemetry / Telecommand interfaces
  • Mechanical flexibility to meet instrument constraints

Project of reference:
Lisa Pathfinder

The LISA Pathfinder mission objective is to demonstrate the suitability of the technology that will be used on the future LISA mission to detect gravitational waves in space.

This project is a good reference of a custom designed unit for scientific payload instrument that includes several electronic designs modules functions (RF amplifiers, power electronics, signal conditioning, control loops, detectors, etc.)

ERZIA has already provided three units (Flight Models and a Spare Model) that have been already integrated on the Acousto Optic Modulator, inside the Lisa Technology Package.

The objective of our units is to amplify a HF RF signal with very tight specifications in terms of power efficiency and noise. In detail:

  • 3 stage SSPA
  • Included variable attenuator for signal leveling
  • Included power detector
  • Linearizers for attenuation and power meter signals
  • Harmonics rejection
  • Optimized efficiency

The units are placed on the RF path that feed the Laser unit, having a critical role on the whole systems.
