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 e xcellent contact-to-contact and pole-to-
pole isolation.This ground shield provides a ground interface
that results in improved high-frequency performance as well
as parametric repeatability. The GRF180 extends
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
switch matrices, automated test equipment, spacecraft and
other applications that require dependable high-frequency
signal fidelity and perfor mance. 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.
Unique features and manufacturing techniques include:
• Positive mounting means to RF ground plane.
• Unique uniframe design provides 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.
• Gold-plated precious metal allo y contacts ensure reliable dc
and RF signal s witching, as well as low and stab le insertion
loss.
• Robust to high temperature solder reflow environments.
PRINCIPLE OF OPERATION
Energizing Coil A produces a
magnetic field opposing the
magnetic field of the
permanent magnet in Circuit
A. As the net holding force
decreases, the attractive
force in the air gap of Circuit
B, which also results from the
magnetic field of the
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 remov al of pow er from Coil A, but will snap bac k 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.
