Teledyne Relays Announces New SGRF300/SGRF303 DPDT Relay Series
New Non-Latching SGRF300/SGRF303 Relay with Signal Integrity Performance Measured up to 18Gbps
Hawthorne, CA, April 2013: Teledyne Relays introduces the SGRF300/SGRF303 family!
The ultraminiature SGRF300 and SGRF303 relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. SGRF300 and SGRF303 relays feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. The SGRF300/SGRF303 version with the improved ground connections can push the performance up into the 18Gbps data rates for digital signal integrity applications. This ground shield provides a ground interface which results in improved high-frequency performance as well as parametric repeatability. The SGRF300 and SGRF303 extend performance advantages over similar RF devices that simply offer formed leads for surface mounting. These relays are engineered for use in RF attenuator, RF switch matrices, ATE and other applications that require dependable high frequency signal fidelity and performance.
The SGRF300 and SGRF303 feature: high repeatability, broader bandwidth, metal enclosure for EMI shielding, high isolation between control and signal paths and high resistance to ESD.
The Series SGRF300D/SGRF303D and SGRF300DD/SGRF303DD relays have internal discrete silicon diodes for coil suppression and polarity reversal protection. This hybrid package reduces required PC board floor space by reducing the number of external components needed to drive the relay. The SGRF300/SGRF303 is available in the SGRF300D/SGRF303D model with an internal diode for coil transient suppression and SGRF300DD/SGRF303DD with internal diodes for coil transient suppression and polarity reversal protection.
The SGRF300/303 Series measures .370 x .340 x .335 inches (9.4, 8.64, 8.51 cm) and weighs .1 ounce (2.9g).
