Space-qualified RF hardware for satellite missions

At mmWave, loss, phase noise, and packaging stack the deck against schedules. Teams burn weeks chasing drift and matching. QuinStar delivers integrated sources, amps, and front-ends that hold spec—so you can focus on the mission, not the plumbing.

mmWave unlocks resolution, bandwidth, and compact apertures across sensing and comms—with hardware that ships on schedule.

Overcome mmWave Challenges—Phase Noise to Lead Times

THE PROBLEM

  • Phase noise at high-GHz—multiplication chains amplify every dBc of source noise, killing system performance
  • Loss & matching headaches—waveguide transitions, connectors, and packaging eat signal at mmWave frequencies

THE SOLUTION

  • Low-noise sources with disciplined multiplication that maintain spectral purity through the chain
  • Proven waveguide components and integrated front-ends with characterized loss and optimized matching
  • Stocked subassemblies and predictable builds to de-risk lead times

Frequently Asked Questions

We can review your link budget and recommend component configurations that optimize NF, gain, and linearity for your W-band application.

Packaging designed for thermal drift management with modeled thermal paths. We address heat dissipation, stability, and environmental robustness in every design.

Disciplined source design and carefully staged multiplication minimize phase-noise degradation. We provide measured data at each stage for your link budget analysis.

Provide your frequency band, output power, phase noise requirements, link budget constraints, environmental specs, and schedule. We’ll scope a solution.

We follow ITAR/EAR processes and turn NDAs around quickly. NDA available on request for all discussions.
