DESCRIPTION

The Series GRF180 relay is the first hermetically sealed,

ultraminiature RF relay designed from inception for surface

mount applications. This magnetic-latching relay features

extremely low internal circuit losses for exceptional time and

frequency domain response characteristics through and

beyond the UHF spectrum and into the S band. The GRF180

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 high-frequency performance as well

performance advantages over similar RF devices that simply

offer formed leads for surface mounting.

The GRF180 is robust to shock, vibration and temperature

extremes for use in space applications and other demanding

environments. It is engineered for use in RF attenuators, RF

PRINCIPLE OF OPERATION

Energizing Coil A produces a

magnetic field opposing the

magnetic

permanent magnet in Circuit

A. As the net holding force

decreases,

force in the air gap of Circuit

B, which also results from the

magnetic

permanent magnet, becomes

great enough to break the

armature free of Core A, and

snap it into a closed position against Core B. The armature remains in this

position upon removal of power from Coil A, but will snap back into position

A upon energizing Coil B. Since operation depends upon cancellation of a

magnetic field, it is necessary to apply the correct polarity to the relay coils

as indicated on the relay schematic.

When latching relays are installed in equipment, the latch and reset coils

should not be pulsed simultaneously. Coils should not be pulsed with less

than rated coil voltage and the pulse width should be a minimum of three

times the specified operate time of the relay. If these conditions are not

followed, it is possible for the relay to be in the magnetic neutral position.

signal fidelity and performance. Its low profile and .100" grid

spaced terminals make the GRF180 ideal for applications

where extreme packaging density and/or close PC board

spacing are required.
