Tenders Are Invited For Re-Issue 400W X Band Gan Sspa For Eo (Expro+)

Tenders Are Invited For T112-801Gs Re-Issue 400W X Band Gan Sspa For Eo (Expro+) Currently Used X Band Solid State Power Amplifiers In Estrack Network Are Designed To Operate Inside The Antenna Equipment Room (Aer) Thus, Do Not Offer The Sturdiness Required For Their Deployment Within The Antenna Apex. Additionally, Uplink Capability Is Limited In The Science Band To 7145Mhz - 7235 Mhz While Eo Missions Require Operations In The Recently Extended Frequency Range 7190Mhz - 7250Mhz. The Development Of The New X Band Sspa Takes Into Account The Need For Compact Overall Size, Broader Environmental Temperature Range And The Robustness To Cope With Operations Under Tilted Positions, Acceleration And Deceleration And The High Vibrations Present In Apex. Previous Designs Favored Gaas Technology Due To Reliability Considerations. However, Market Is Now Mature For The Deployment Of Gan Devices That Also Allow Size Reduction Thanks To The Increased Efficiency. The Weak Points Of A Power Amplifier Can Usually Be Identified In The Power Modules That Are Combined Together To Achieve The Rated Rf Power And In The Power Supply. Modularity Concept Shall Be Adopted Enabling In Such A Way Soft Degradation And Therefore Operations Also Under Derated Outputpower.The New Design Developed In This Activity Is Based On A Broad Redundancy Concept Incorporating Driver Amplifiers, Power Suppliers And Power Modules. The Modularity In Combination With The Redundancy Model Ensures Attainment Of Rated Power Also In The Eventuality That One Module (Power Supply Or Power Module) Fails Thus, Increasing The Uplink Availability. As Part Of The Project A Tradeoff Between Air Cooling And Water Cooling Shall Be Investigated. Water Cooling Is Indeed More Efficient (Mainly At High Altitude), Less Noisy And May Reduce Further The Overall Size Of The Amplifier (One Of The Challenges Compared To The Previous Development) On The Other Hand Air Cooling Is Less Cumbersome To Deploy In The Antenna Apex And Has No Implications Deriving From The Acceleration/Deceleration And The Angled Orientation The Sspa Will Be Subjected.Procurement Policy: C(2) = A Relevant Participation (In Terms Of Quality And Quantity) Of Non-Primes (Incl. Smes) Is Required.
