DESCRIPTION

The GRF172 surface-mount Centigrid? relay is an ultraminiature,

hermetically sealed, armature relay for 2.5 GHz RF applications.

Its low profile height (.330”) and .100” grid spaced terminals make it

an ideal choice where extreme packaging density and/or close PC

board spacing are required.

The GRF172 features a unique ground shield that isolates and

shields each lead to ensure excellent contact-to-contact and

pole-to-pole isolation. This ground shield provides a ground

interface that results in improved highfrequency performance as

well as parametric repeatability. The GRF172 extends performance

advantages over similar RF devices that simply offer formed leads

for surface mounting.

Unique construction features and manufacturing techniques

provide overall high reliability and excellent resistance to

environmental extremes:

? All welded construction.

? Unique uni-frame design providing high magnetic efficiency and

mechanical rigidity.

? High force/mass ratios for resistance to shock and vibration.

? Advanced cleaning techniques provide maximum assurance of

internal cleanliness.

? Precious metal alloy contact material with gold plating assures

excellent high current and dry circuit switching capabilities.

Applications include telecommunications, test instruments, mobile

communications, attenuators, and automatic test equipment.
