Fixed and Offset Short Circuits

Precision 3.5mm/SMA Reference
Plane and Fixed Short Circuits

Description

The 360D (female) and 360B (male) are true coplanar, reference plane shorts that mate with 3.5mm, SMA and 2.92mm (K) connectors and can be used at frequencies up to 40 GHz. The 360D, in particular, represents a true advance in the state-of-the-art. Prior to its introduction, the typical SMA mateable female short would exhibit a return loss in excess of 4 dB at 18 GHz. The return loss of the 360D at
18 GHz is generally less than 0.02 dB with a phase offset of less than 0.2 degrees.

Features

• DC TO 40 GHz
• Mates With 3.5mm, SMA and 2.92mm

Precision 3.5mm Fixed Short Circuits

Description

The 8046F and 8047F are precision 3.5mm fixed shorts designed to operate from DC to 34 GHz. These shorts, although classified as "fixed", establish a measurement plane of 0.500cm offset from the connector reference plane for compatibility with the companion 8048 series open circuits. The 8046 and 8047 series of offset shorts are referenced to this offset. The 8046F and 8047F are used in several popular 3.5mm VNA calibration kits in use today.
