What Polarity, Inc. does
Polarity, Inc., founded in 1999 and headquartered in Rancho Cordova, California, designs and manufactures high-voltage power systems and RF/microwave amplifiers for military, industrial, commercial, and green-power applications. The company's product portfolio spans pulsed and CW Traveling Wave Tube (TWT) amplifiers from 500W to 150kW, Klystron transmitters (including 500kW S-Band units), GaN-based Solid State Power Amplifiers built on Qorvo's patented Spatium Technology, high-voltage solid-state modulators (500V to 100kV, with modulation rates up to 1-2MHz), HV DC-to-LV DC converters (10W to 10kW), HV microwave tube test sets, airborne and shipboard TWT power supplies rated for >50,000ft altitude, and high-efficiency transformer-less PV inverters exceeding 100kW. The company also operates custom design and fabrication services, with in-house capabilities spanning power-electronic, analog, and digital circuit design, thermal and mechanical engineering, and environmental testing for shock, vibration, altitude, and salt-fog compliance. Customers include the US military, defense primes such as Raytheon Missile Systems, satellite communication operators, and industrial/scientific research facilities, with named use cases in electronic warfare (EW), electronic countermeasures (ECM), radar, satellite communications, and microwave tube manufacturing.
The business operates on a quote-based, custom-solutions pricing model with no public price list, supported by a hybrid go-to-market combining direct technical sales from the Rancho Cordova headquarters with a network of regional sales representatives covering five US territories and international reps in Italy, Switzerland, Spain, Portugal, Taiwan, India, and South Korea. Revenue is generated through hardware sales of both standard catalog products and fully customized systems, plus professional services for custom design and fabrication. Polarity holds AS9100D aerospace and ISO 9001 quality management certifications (with ANAB accreditation), positioning the firm as a qualified supplier into defense and aerospace supply chains. Founded 25+ years ago by what the company describes as engineers with 40+ years of high-power microwave experience, Polarity remains privately held with no disclosed institutional investors, no parent company, and no public-market presence.
The firm competes in niches defined by harsh-environment reliability rather than scale: airborne and shipboard defense electronics, ground mobile EW/ECM subsystems, industrial microwave tube testing, and increasingly adjacent commercial verticals such as EV high-voltage power conversion and UAV tethered-power systems. Its competitive position rests on the combination of regulatory certifications, engineering tenure, and proprietary integration know-how (e.g., MTBF/MTTR-driven design and 3μs electronic crowbar fault protection) rather than on volume manufacturing, with the company explicitly positioning as a specialist supplier whose designs are embedded in major EW, ECM, radar, communication, and test equipment systems worldwide.
