GaN SSPA Solutions for Satellite Broadcast
Celestia TTI delivers a unique portfolio of high-power Solid State Power Amplifiers (SSPAs) and Block Up Converters (BUCs) based on Gallium Nitride (GaN) technology, purpose-built for the satellite broadcast industry. From tens of watts up to several kilowatts, our systems maximise linear power and provide outstanding performance for multicarrier uplinks across DBS, Ku and C frequency bands.
With hundreds of GaN SSPAs deployed at teleports and broadcast facilities worldwide, operating 24/7 under the most demanding environmental conditions, Celestia TTI has built a proven heritage of reliability that broadcast operators depend on for mission-critical uplink services.
Why GaN SSPA Technology for Broadcast?
Broadcast satellite operators face increasing pressure to deliver more bandwidth with higher efficiency while reducing operational costs. GaN-based SSPAs offer decisive advantages over legacy Travelling Wave Tube (TWT) amplifiers that directly address these challenges.
Multicarrier Performance
Our SSPAs support an unlimited number of carriers with flexible frequency separation, delivering significantly less back-off than TWTs. This translates to higher usable power per carrier for DTH uplinks, contribution feeds and satellite newsgathering (SNG) applications.
Modularity and Scalability
Phase combination of SSPA modules enables systems to grow in power at any time, providing capital investment flexibility. Built-in redundancy with hot-swappable modules ensures uninterrupted service. Available configurations include 1:0, 1:1 and 2:1 redundancy schemes.
Operational Savings
GaN technology delivers considerable electricity savings for multicarrier high-power uplinks. Combined with superior MTBF figures, simplified maintenance and graceful degradation capability, broadcast operators achieve significant OPEX reductions compared to TWT-based systems.
Broadcast Product Portfolio
SSPAs and BUCs
Our broadcast-optimised amplifier families cover the primary satellite uplink bands used by teleports and broadcasters globally:
- DBS-band SSPAs/BUCs — High-power amplification for direct broadcast satellite uplinks at 17.3–18.4 GHz, with models delivering up to 550 W linear power.
- Ku-band SSPAs/BUCs — Industry-leading performance at 13.75–14.5 GHz for contribution, distribution and SNG applications, with outputs from 80 W to 600 W.
- C-band SSPAs/BUCs — Robust solutions for C-band uplinks, valued for rain-fade resilience in tropical regions and long-haul broadcast distribution.
Low Noise Amplifiers and Frequency Converters
Complete your broadcast RF chain with our LNAs and LNBs for optimal receive-side performance, and our outdoor frequency converters for flexible frequency translation in broadcast ground stations.
Broadcast Applications
DTH Satellite Uplinks: High-power, multicarrier uplink systems for direct-to-home television distribution, supporting HD, UHD and next-generation broadcast formats with the linear power headroom that demanding modulation schemes require.
Teleport Operations: Scalable SSPA systems that grow with operator demand, supporting multiple satellites and transponders from a single facility while maintaining the redundancy levels that 24/7 broadcast SLAs demand.
Satellite Newsgathering (SNG): Compact, field-deployable SSPA/BUC units for mobile satellite newsgathering, delivering reliable uplink performance from remote locations under challenging conditions.
Contribution and Distribution: End-to-end RF solutions for programme contribution links between studios, production facilities and satellite uplink centres, ensuring signal integrity throughout the broadcast chain.
