About the series
What it is
Precision adapters for transitioning between coaxial interfaces: 50 Ω, threaded or push-on coupling depending on the pair.
The part number is composed of two interfaces with gender indicated: M — plug, F — socket (2.4M-2.92F — 2.4 mm plug to 2.92 mm socket; FKF — flange-mount socket-to-socket feedthrough).
VSWR by pair
- 1.85 ↔ 1.85 mm: < 1.3 up to 67 GHz; 1.85 ↔ SSMP and SMP: < 1.2 and < 1.3 up to 40 GHz; 1.85 ↔ 2.4 mm: < 1.2 up to 50 GHz.
- 2.4 ↔ 2.92 mm: < 1.15 up to 40 GHz; 2.4 ↔ 3.5 mm: < 1.12 up to 26.5 GHz; 2.4 ↔ SMP: < 1.3 and 2.4 ↔ SSMP: < 1.2 up to 40 GHz.
- 2.92 ↔ SMP: < 1.3; 2.92 ↔ SSMP: < 1.2 up to 40 GHz; 2.92 ↔ 3.5 mm: < 1.12 up to 26.5 GHz.
- 3.5 ↔ 3.5 mm: < 1.12 up to 26.5 GHz; 3.5 ↔ BMA and SBMA: < 1.15 up to 18 GHz.
- N ↔ N: < 1.12 up to 18 GHz; N ↔ 2.92 and 3.5 mm: < 1.12 up to 18 GHz; N ↔ TNC: < 1.2 up to 11 GHz; TNC ↔ 3.5 mm: < 1.2 up to 11 GHz; BNC ↔ N: < 1.15 up to 4 GHz.
- 1.0 ↔ 1.85 mm and 1.0 ↔ 2.4 mm — full series of gender combinations.
Where it is used
Test benches and calibration: transitioning from an instrument port to a cable or device under test without loss of accuracy; mating units with different interfaces.

Questions and answers
How is an adapter part number read?
Two interfaces with gender: 2.4M-2.92F — a 2.4 mm plug on one side and a 2.92 mm socket on the other; NM-TNCF — N plug to TNC socket; N-FKF — flange-mount N socket-to-socket feedthrough.
What is the VSWR of the adapters?
From < 1.12 for the 2.4/3.5, 2.92/3.5, N/N, N/2.92, N/3.5 pairs to < 1.3 for pairs with SMP and for 1.85/1.85 mm — across the band of each pair.
Are there adapters with 1.0 mm?
Yes: 1.0 ↔ 1.85 mm and 1.0 ↔ 2.4 mm in all gender combinations.
