Description
Introduction
This between series 2.4mm to 3.5mm adapter was developed for use to 34 GHz. It uses a Passivated Stainless Steel body and gold plated contact pin. It has low VSWR and low loss to use to 34GHz. 2.4mm to 3.5mm adapter is constructed with male gender on end 1 and female on end 2. Usually VNA ports or test cable assemblies are designed as 2.4 mm series, it's good to take this adaptor for interface transformation, then you can test SMA, 3.5 mm products directly after calibration.

FAQ
1. Hualink 3.5 mm Connectors
3.5mm RF coaxial connectors have a working frequency up to 34GHz, The 3.5 mm connector is a pin and socket design developed for use as an instrument grade air dielectric connector. The design configuration allows the 3.5 mm connector to mate with both SMA and the 2.92 mm connector.
2. How to use an adaptor?
Adapters are used to make reliable transitions from one connector interface to another. They are typically used for test and measurement, between equipment mounted connectors and devices under test. Adapters are available in-series and between series. Push-on versions are also available with slide-on interface instead of screw-on allowing significant time saving. Hualink also provide quick adaptors. They provide increased test speed, higher test coverage and maximum through-put.
