RF & MICROWAVE SERIES SURFACE MOUNT, MAGNETIC-LATCHING BROADBAND RF RELAYS DPDT 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-topole 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 GRF180 switch matrices, automated test equipment, spacecraft and other applications that require dependable high-frequency 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. 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 alloy contacts ensure reliable dc and RF signal switching, as well as low and stable insertion loss. * Robust to high temperature solder reflow environments. PRINCIPLE OF OPERATION PERMANENT MAGNET MAGNETIC CIRCUIT A Energizing Coil A produces a SOFT IRON CORE A magnetic field opposing the MAGNETIC CIRCUIT B SOFT IRON FRAME magnetic field of the permanent magnet in Circuit COIL A COIL B A. As the net holding force decreases, the attractive force in the air gap of Circuit AIR GAP B, which also results from the STATIONARY CONTACT magnetic field of the permanent magnet, becomes great enough to break the MOVING ARMATURE CONTACT 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. ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS -65C to +125C Temperature Storage (Ambient) Operating -55C to +85C Vibration (General Note 1) 30 g's to 500 Hz Shock (General Note 1) 100 g's, 6 msec, half-sine Enclosure Hermetically sealed Weight 0.10 oz. (2.9g) max. 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.
