Spacetime Engineering

What Spacetime Engineering does

Spacetime Engineering, founded in 2013 and headquartered in Harbor City, California, manufactures RF components and antenna feeds for the satellite communication ground segment, spanning frequencies from 1 GHz to 140 GHz. Its core products include antenna feeds (2-port to complex multi-band, multi-polarity, multi-port configurations), RF components, custom feed upgrades, and a 4-port feed network product line covering C-Band through Ka-Band in both linear and circular polarization. The company performs vertically integrated in-house design, precision machining, electroforming, and testing for S-parameters, high-power passive inter-modulation, and antenna patterns, and also offers build-to-print manufacturing and engineering services including antenna performance predictions for regulatory certification.

The business operates an enterprise field sales motion backed by a network of regional sales representatives — Decibel Technologies for Asia/Pacific Rim, KM Communications for North America, and Sematron Italia and EuroSatCom for Europe and the Middle East — targeting defense and military customers as its primary vertical and commercial satellite operators as a secondary vertical. Revenue is generated through hardware sales of antenna feeds and RF components, supplemented by professional services such as RF design, analysis, manufacturing, testing, precision machining, and electroforming. Pricing is quote-based with quantity pricing available for standard products.

On September 24, 2025, Spacetime Engineering was acquired by Vitesse Systems, a portfolio company of private equity firm Trive Capital, consolidating Spacetime's multi-band antenna feed expertise into Vitesse's broader Space and Airborne-related antenna portfolio for defense customers. Leadership comprises CEO Hans Spieleder, CTO Dr. Robert Hoferer, and COO Tom Funk, supported by managers in integration and test and materials and processes.

Core offering

Spacetime Engineering designs, manufactures, and tests RF components and antenna feeds for the satellite communication industry. Its core product portfolio includes antenna feeds (multi-band, multi-polarity, multi-port designs), RF components, custom feed upgrades, and specialized engineering services (RF design, analysis, build-to-print manufacturing, precision machining, and electroforming), covering frequencies from 1 to 140 GHz across C-Band, Ku-Band, and Ka-Band. The company sells to defense and commercial satellite communication customers via regional sales representatives and direct contact.

Product overview

Spacetime Engineering is a provider of RF components and antenna feeds for the satellite communication industry. The company operates as a unified product-and-services portfolio organized around four core offerings: Antenna Feeds (state-of-the-art feed configurations from simple 2-port to complex multi-band, multi-polarity, multi-port designs), RF Components (high-quality components from 1-140 GHz with vertically integrated manufacturing), Feed Upgrades (custom-fit solutions for antenna upgrade requirements), and Specialized Services (RF design, analysis, manufacturing, testing, build-to-print, precision machining, and electroforming). The product line spans frequencies from C-Band through Ka-Band in both linear (LP) and circular (CP) polarization configurations, with specific product series including the 4-port feed network product line (part numbers 10055-001, 10050-001, 10012-004, 10015-010, 10114-002) and various 2-port tactical variants. Founded in 2013, the company was acquired by Vitesse Systems in September 2025 to strengthen multi-band antenna solutions for defense applications.
