Starlink’s recent launch of its first 26 Version 3 (V3) satellites points to significant advances in satellite-broadband capacity and user performance. Achieving this level of performance requires high-performance RF components throughout the system.
mmTron’s MMIC power amplifiers, delivering record-setting mmWave linear output power, exceptionally wide modulation bandwidth, and high efficiency, address the demanding RF requirements of next-generation satellite broadband systems.
Starlink’s Version 3 Architecture
Each V3 satellite is designed to provide 1 Tbps of downlink capacity and 160 Gbps of uplink capacity. Phased arrays direct that capacity to ground users through 2,048 downlink beams and 2,048 uplink beams.
The V3 design offers 10× the downlink capacity and 22× the uplink capacity of V2 satellites. The V2 phased arrays provide only 192 downlink beams and 144 uplink beams.
Each V3 satellite also uses six 400 Gbps lasers to route data among satellites. Its gateway backhaul uses four quad-band antennas operating across Ka-, E-, V-, and W-band frequencies. This architecture increases backhaul capacity to 1.2 Tbps—more than 8× that of V2 satellites. The backhaul uplink aggregates 60 GHz of spectrum across four bands and antenna polarizations, yielding a 4.3× improvement over the V2 design.
Enabling High-Capacity Backhaul
High-capacity backhaul at mmWave frequencies requires MMIC power amplifiers that combine high linear output power, wide modulation bandwidth, and high efficiency. Wide modulation bandwidth supports high data rates, while high linearity enables higher-order modulation and more efficient use of available spectrum. Higher efficiency reduces demand on satellite power systems and eases thermal-management requirements.
mmTron develops MMIC power amplifiers that deliver record-setting linear output power at mmWave frequencies, alongside exceptionally wide modulation bandwidth and high efficiency. These capabilities are critical for supporting higher-order modulation, increasing data throughput, and maximizing spectral efficiency in next-generation satellite communication systems.
Our differentiation reflects semiconductor process optimization, including epitaxial layer design; proprietary device models; advanced circuit architectures; and products engineered for demanding satellite applications.
As satellite broadband architectures continue to push the limits of capacity and spectrum utilization, linear output power, modulation bandwidth, and efficiency will be increasingly important RF performance differentiators.
