| ASSMA
SERIES DESIGN FEATURES & SPECIFICATIONS |
|
With
the electronic industry's increased demand for bandwidth and higher frequencies,
combined with the need for smaller packaging and reduced cost,
SGMC Microwave introduces
the ASSMA series. The ASSMA Series is a rugged, sub-miniature connector that
operates from DC to 50 GHz and is mechanically compatible with SSMA connectors.
ASSMA connectors area available for both semi-rigid and flexible coaxial
cable, panel mount and spark plug launchers, and in-series and between-series
adapters.
DESIGN FEATURES:
The ASSMA Series are precision sub-miniature connectors designed for broadband
microwave applications. ASSMA connectors provide excellent performance up
to 50 GHz and have electrical and mechanical compatibility with standard
#10-36 UNS thread connectors such as the SSMA. ASSMA Series connectors are
rugged, sub-miniature in size, and offer the following features:
|
-
Frequency Range - DC-50 GHz
-
Mechanically Compatible with SSMA & ASSMA Connector Series
-
Ruggedized Construction for Repeatability and Reliability
-
Air Dielectric
-
Captivated Center Contact
