Precision 2.92 mm Female to 1.85 mm Female RF Coaxial Adapter, DC–40 GHz

P/N: VST-A-292F185F-01

– DC–40 GHz coverage for cross-series precision measurements
– Female interfaces receive male 2.92 mm and 1.85 mm connectors
– VSWR ≤1.12 supports low-reflection broadband coupling
– 27 mm straight body with dual external interface threads
– Fits VNA cables, fixtures, and component validation paths

Engineering Note
VST-A-292F185F-01 is a female-to-female cross-series RF coaxial adapter for joining male-ended 2.92 mm and 1.85 mm measurement hardware through DC–40 GHz. Its dual receptacle geometry supports cable, fixture, or component coupling where both existing interfaces are male. The 50 Ω design, VSWR ≤1.12, 1000 Vrms dielectric withstand voltage, 27 mm body, and two external interface threads define the adapter’s confirmed electrical and mechanical envelope.

Target Applications

Cross-Series Cable Coupling

Female interfaces on both ends join male-ended 2.92 mm and 1.85 mm test cables or components.

40 GHz VNA Paths

The adapter provides a defined transition from a 2.92 mm path into 1.85 mm hardware within DC–40 GHz.

Precision Fixture Integration

Dual external interface threads support fixtures that expose male ports from the two connector families.

RF Component Validation

The 27 mm straight envelope supports planned inline connections between dissimilar precision interfaces.
