studies of success
Since the Russian LUNA mission in 1976, the Chang’e 3 has been the first human-made artifact to make a soft-land on the Moon in the recent years. The mission itself is a first step for the development and testing of new technologies for future lunar missions, collecting data from the surface with the different sensors and cameras included on the rover called “Yutu”.
ERZIA has designed and manufactured four state-of-the art amplifiers, which are a critical part of the Yutu scientific instrumentation. We are very proud of being part of this important milestone that could hopefully be the first of a series of future missions to the earth’s natural satellite.
The LISA Pathfinder mission objective is to demonstrate the suitability of the technology that will be used during 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.

PAZ (peace in Spanish), formerly known as SEOSAR/PAZ (Satélite Español de Observación SAR - SAR Observation Spanish Satellite), is an X-band SAR (Synthetic Aperture Radar) mission of Spain, in fact a flagship mission of the Spanish Space Strategic Plan 2007-2011.
PAZ is an X-band SAR (Synthetic Aperture Radar) spacecraft based on the TerraSAR-X platform, to serve the security and the defense needs. The PAZ mission is a dual-use mission (civil/defense) funded and owned by the Ministry of Defense and managed by Hisdesat.
ERZIA has designed and manufactured several EGSE equipment used in different stages from platform manufacturing to launch site operations, including both RF and Power equipment.
EXOMARS: 225 000 000 km from earth
This mission to the red planet includes an Orbiter, which will carry a scientific trace gas payload instrumentation and an Entry, Descent and Landing (EDL) Demonstrator. The main objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological processes and to test key technologies in preparation for future mars missions.
ERZIA has designed and manufactured two RF amplifiers located on the scientist payload. The unique performance of this instrument required a special RF design were low power consumption was critical, while maintaining the best possible performance.
