UNSPSC 32101535: Phase modulation circuit

A circuit network that makes the phase modulation wave with the phase changes, and simultaneously, the amplitude is also changed that it is refined with certain amplitude through the amplitude limiter and synthesizes the phase modulation circuit by the vector synthesis to the modulation wave with the changing size.

UNSPSC 32101535 Phase modulation circuit is a Commodity code, but the recent state and local opportunities tagged with this code show minimal alignment with its nominal scope. The School Board of Hillsborough County, Florida issued an ITQ for inspection, installation, and repair services for vehicle camera, navigation, ridership, and communication systems across a fleet serving approximately 225,000 students, with 24 line items covering DVR and camera systems, GPS units, vehicle tablets, AIM modules for fuel and DEF monitoring, RFID systems, two-way radio systems, and illuminated stop-arm and bus-ID systems. The City of Phoenix issued an IFB for turnkey emergency responder radio coverage system design, installation, testing, and post-installation optimization using bi-directional amplifiers, distributed antenna systems, and related equipment compliant with NFPA 1225 and UL 2524 standards across city buildings and three airports, with a five-year contract term commencing August 25, 2026 and DBE-Neutral set-aside requirements. Santa Clara County issued two RFQs for Motorola radios and accessories for the Office of the Sheriff. Sourcewell, a Minnesota cooperative, issued an RFP for law enforcement equipment on behalf of participating entities in Washington, Franklin, Grant, Grays Harbor, Chelan, and Yakima counties. The Texas A&M University System issued an RFP for design, purchase, installation, and commissioning of an IP-based operational communications system for the Ballistic, Aero-Optics, & Materials Range at its Bryan, Texas campus, with a two percent VetHUB subcontracting goal for contracts valued at $100,000 or more. These opportunities span school districts, city and county government, state cooperative purchasing entities, and higher education, though the actual work involves systems integration, installation, and maintenance of communications and vehicle-mounted equipment rather than phase modulation circuits per se.

Recent activity appears primarily in Florida, Arizona, California, Texas, Minnesota, and Washington. The Hillsborough County ITQ response date is listed as June 3, 2026; the Phoenix IFB response date was July 10, 2026; Santa Clara County's RFQs were due July 24, 2026 (posted July 16) and June 17, 2026 (posted June 9); Sourcewell's RFP was due June 16, 2026; and Texas A&M's RFP response was due April 6, 2026, with written questions due March 26, 2026. The mismatch between the code's name and the actual work being procured suggests that state and local procurement offices may be misclassifying these opportunities or that the code itself encompasses a broader range of communications and vehicle electronics work than the phase modulation label suggests. The code shows recent activity but limited alignment with its nominal product category.
