Series LB363/GLB363 LoopBack Relay Up to 12Gbps LoopBack Relay LB363 Series GLB363 Series SERIES DESIGNATION LB363 GLB363 RELAY TYPE LoopBack Relay, Sensitive Coil LoopBack Relay, Ground Shield, Surface-Mount (Stub Leads), Sensitive Coil DESCRIPTION The LoopBack Series relay combines two DPDT electromechanical relays in one package that includes an internal bypass path for Automated Test Equipment (ATE) applications. The LoopBack combines the technology of two Teledyne RF/GRF300 Series relays which eliminates the need for external PCB traces in loop back test applications. This innovation results in superior signal integrity and RF performance, while taking minimal board space. The LB/GLB363 Series is designed for digital signaling application and provides excellent signal integrity up to 12 Gbps data rates. The LoopBack relay is available with two different internal paths: Through and AC Bypass. The Through version provides a loop back path across high performance contact material, while the AC Bypass Model adds a coupling capacitor across each loop back path. The internal in-line capacitors allow you to eliminate the footprints for external components, while performing AC bypass functions internal to the relay. The capacitors used feature excellent signal integrity as well as low loss high frequency performance. receiver of the DUT. The double pole design of the LoopBack relay is perfectly suited for differential signaling, allowing relay component to provide transmit and receive signals and their inversions to the DUT or through the bypass path. The internal structure of the LoopBack relay reduces the number of discontinuities and shortens the signal path during loop back testing, providing lower insertion loss and higher signal integrity performance than two RF/GRF303 Series relays. In the normally closed mode (de-energized) the LoopBack relay provides four normally closed contacts. When energized, the moving contacts are connected together across the loop back structure to provide two through paths. The normally closed contacts have similar performance to RF/GRF303 Series relays. In addition to the thru-hole mount, the LoopBack Series relay is available in through hole surface mount stub leads with a ground shield. The surface mount ground shield used in the stub lead provides improved high data rate and high frequency performance, as well as improved repeatability. Upon request, various ground pin configurations for through lead models are available. A typical loop-back load board application uses the Device Under Test (DUT) to test itself. In this method, the transmitter from the DUT is connected through a loop back path to the ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) Storage –65°C to +125°C Operating –55°C to +85°C Vibration (General Note 1) Weight © 2011 TELEDYNE RELAYS LB363 Enclosure Hermetically sealed 10 g’s to 500 Hz Shock (General Note 1) 30 g’s, 6ms half sine 0.16 oz.
