SMA Inc manufactures SubMiniature version A (SMA) connectors, semi-precision coaxial RF connectors with 50 Ω impedance and screw-type coupling mechanisms. Originally designed for DC to 12 GHz applications in the 1960s, the technology has evolved with variants supporting frequencies up to 26.5 GHz. The connectors are widely used in microwave systems, mobile antennas, WiFi systems, radio astronomy, and software-defined radio applications. Signal Plug searches live against smainc.com's mail server to find and verify email addresses for any SMA Inc employee.
Signal Plug searches live against smainc.com's mail server — not a static database. Get a verified email for any SMA Inc employee with confidence score in under 2 seconds.

Competitive Advantage
SMA connectors were engineered in the 1960s and remain a semi-precision standard six decades later; the connector's minimal interface design became foundational for RF coaxial cable connections; mechanically compatible variants like K-connectors demonstrate SMA's extensible architecture to vastly higher frequencies (40 GHz vs. original 12 GHz); SMA is specifically preferred in radio astronomy at frequencies 5 GHz and above; the technology bridges both legacy DC applications and modern high-speed wireless systems including WiFi and software-defined radio.

Most email finder tools pull from static databases of scraped email addresses. These databases go stale as people change jobs and companies update their email infrastructure. Signal Plug takes a different approach: every search performs a live check against smainc.com's mail server using SMTP verification. This means results reflect the current state of SMA Inc's email system — not a cached result from months or years ago.
Signal Plug enriches every result with supporting data: a confidence score (0–100), deliverability status (Valid, Risky, or Catch-all), job title where available, and LinkedIn profile URL. This context helps you prioritize which SMA Inc contacts to email first and personalize your outreach before you hit send. Plans start at $29/month for 500 searches — no annual contracts or seat fees.
