Product Overview
The Pomona 72966 is an in-series coaxial adapter joining two SMA male plugs. Engineered for 50-ohm RF systems operating from DC up to 18 GHz, it features gold-plated brass body construction, gold-plated beryllium copper female contacts, and a PTFE dielectric insulator. A knurled center section provides positive finger grip for secure hand tightening during test bench setup and RF line assembly.
Key Features
- Adapter Configuration: In-series SMA jack (female) to SMA jack (female) straight barrel
- Impedance: 50 Ohms
- Frequency Range: DC to 18 GHz
- Housing: Machined brass with gold plating and knurled center grip

- Overall Length: 0.87 in (22.0 mm)
Applications
- Coupling two male SMA patch cables together to extend run length on an RF test bench
- Serving as a sacrificial connector saver on expensive spectrum analyzer or signal generator test leads
- Connecting SDR receivers, ham radio gear, and GPS antennas in maker bench setups
Frequently Asked Questions
What are the interface types on this adapter?
Both ends are standard SMA jacks (female sockets) with external 1/4-36 threads, designed to accept standard SMA plugs (male pins with internal threads).
What is the frequency limit of the Pomona 72966?
This adapter is rated for operation from DC up to 18 GHz at 50 ohms impedance.
Why buy individual adapters here instead of a generic bulk lot?
Genuine Pomona RF hardware delivers consistent 50-ohm impedance and reliable DC-18 GHz performance without the plating flaws and mismatched tolerances common in unbranded bulk imports. You get the exact count needed for your project, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free at $28 or more, and leave our Idaho warehouse the same or next business day.
Clean gold plating, true 18 GHz bandwidth, and the steady grip of proper knurling make this little Pomona barrel the quiet hero of any high-frequency test bench. Thread it into the line and let your signals run clean.
