Description
Introduction
Hualink provides a full range of in-series and between - series high performance, high quality, precision adaptors, it performs very low VSWR and insertion loss. These 2.92mm to SMPM/SSMP/GPPO adaptors are designed in very stringent tolerances, manufactured following strict procedures, and checked completely. Heat treated gold plated beryllium coppers center pin and body ensure that adaptors have better "anti-corrosion", "wear-resisting" to reach more mating/unmating cycles. And SMPM push-pull design allows it to connect or disconnect quickly, SMPM small size allow it to use in small space, floating interface design allows it meet blind application.

FAQ
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.
Hualink's SMPM Series
SMPM series connectors, also known as Mini-SMP, are similar in structure to SMP series. They adopt smart snap/Snap-on connection. With smaller size, their working frequency can be up to 67 GHz. They are widely used in communications, Automobile, satellite, radar, radio astronomy and other fields. The dielectric is the air. The structure is simple and the volume is small, which can maximize the performance in the most compact space and reduce the weight of the system while providing excellent reliability. The interface is compatible with GPPOTM and SSMP series connectors.
