Pole/Zero

What Pole/Zero does

Pole/Zero designs and manufactures RF/microwave interference mitigation and spectral purification hardware for defense, space, GPS, aerospace, communications, and automated test equipment markets. Founded in 1989 in Cincinnati, Ohio by a father-and-son team of electrical engineers, the company is now operated as a brand within Microwave Products Group (MPG), a division of Dover Corporation. Its product portfolio centers on tunable and fixed-frequency filters (bandpass, bandreject, highpass, lowpass, multiplexers), complemented by low noise amplifiers, cosite interference mitigation equipment, cosite power amplifiers, a broad family of RF switches (coaxial, waveguide, space-qualified, high-power, high-repeatability), receivers, frequency converters, switch matrices, switched filter banks, cancellers, RF distribution systems, and subsystems/IMAs. The company also offers the Spectrum Operations product line (teamSENTINEL, teamSOIGNE) for spectrum monitoring, alongside the FilterWizard® web-based product selection tool. Supporting technology includes the SPECTRASYS RF architecture simulator and Eagleware GENESYS RF/Microwave design tools for filter and circuit design. The company reports over 200 space-qualified product designs with NASA and ESA approval and 75+ years of combined space heritage.

Pole/Zero serves primarily defense and military integrators, with primary use cases including airborne command posts, jet fighters, UAV payloads, ground and mobile communication systems, maritime warships, missile GPS, and spacecraft RF systems. The company is AS9100D and ISO 9001:2015 certified, with IPC-A-610 and J-STD-001 trained personnel, positioning it as a qualified supplier into aerospace and defense prime contractor supply chains.

Revenue is generated through direct sale of custom-engineered RF hardware and integrated subsystems to defense manufacturers and RF/microwave electronics integrators. The company operates a B2B enterprise field sales model with quote-based pricing determined per program via its sales engineering team, structured around multi-year contracts. Products are designed to specific customer requirements with the goal of maximizing overall system-level RF performance, particularly in cosite environments where multiple radios must operate simultaneously without interference. Marketing channels combine direct sales engagement, technical literature, online product finder tools, and the FilterWizard® design assistant. Pole/Zero distributes globally through MPG's direct enterprise sales force and global rep firm network.

Revenue model

1. RF Component Hardware Sales: Pole/Zero generates revenue through the design, manufacture, and sale of RF interference mitigation hardware including filters, switches, amplifiers, and integrated subsystems. Products are sold directly to defense manufacturers and RF/Microwave electronics integrators with custom engineering support. Revenue is primarily from one-time hardware purchases with potential for follow-on orders and spare parts.
