studies of success
Since the Russian LUNA mission in 1976, the Change'e 3 is the first man-made instrument to make a soft landing on the moon. The mission itself was a first step in developing and testing new technologies for future lunar missions and collecting data from the surface with the different sensors and cameras on the Yutu rover.
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 we hope will be the first in a series of future missions to the earth’s natural satellite.
The objective of the LISA Pathfinder mission is to demonstrate its ability to detect gravitational waves in space.
This project demonstrates a good example of a device custom-designed for a scientific payload instrument that includes several electronic modules and 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 already been integrated into the Acousto Optic Modulator, within the Lisa Technology Package.
Our objective is to amplify an HF RF signal within very tight power efficiency and noise specifications. In detail:
- Three-stage SSPA
- Variable attenuator for signal leveling
- Power detector
- Linearizers for attenuation and power meter signals
- Harmonics rejection
- Optimized efficiency
The units are placed in the RF path that feeds the laser unit and play a critical role within the whole system.

PAZ (peace in Spanish), formerly known as SEO-SAR/PAZ (Satélite Español de Observación, which means Spanish Observation Satellite - Synthetic Aperture Radar), is a Spanish X-band SAR mission, the flagship mission of the Spanish Space Strategic Plan from 2007-2011.
PAZ is based on the TerraSAR-X platform, to serve security and defense requirements. 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 instruments for different stages, from platform manufacturing to launch site operations, including both RF and power equipment.
EXOMARS: 225,000,000 km From the Earth
This mission to the red planet includes an orbiter, which will carry a scientific trace gas instrument 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 may 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 for the scientific payload. The unique performance of these instruments requires a special RF design in which low power consumption and high performance are critical.
