Teledyne Relays – All Current New Products

Teledyne Relays, over the past year, have expanded our product lines to meet current and future market requirements. Our excellence in engineering ground breaking technology has been extensive for more than 60 years and we have continued this feat with our latest range of products.

EMR
We have released two new families into our EMR product lines; the RF121/GRF121 & RF700/RF703.

The 121 series boast excellent frequency handling capabilities; up to 16GHz, making it ideal for all X-Band systems, HF Spread Radios, ATE and many other applications. Reliable switching is ensured by precious gold-plated metal alloy contacts.

Our RF700/RF703 was designed with High Repeatability, due to the uniframe motor design, and Broader Bandwidth (Than its little brother, RF300). These DC-4GHz EMR’s are ideal for applications such as RF Attenuation, RF Switch Matrices, ATE and many others. Options for coil suppression diodes are available for applications where the control circuits could be liable to back EMF damage.

COAX
We have release a new family to our coaxial switching lines; our CCR-48K/CR-48K. This SPmT (m=3-6) switch has frequency handling of DC-40GHz and boasts excellent RF Characteristics. It comes as standard with 2.92mm K-Connectors to enable excellent performance in the higher frequencies of its bandwidth. Suitable for operation with TTL Drivers and D-Sub Connectors, options available. Also, the option for coil suppression diodes and moisture seals are available.

Ideal for applications such as Electronic Warfare, ATE Systems and Satellite Communications

Military Solid State Relay
This year we have released our LD00KM & LD00KQ, 270VDC @ 10A & 20A, respectively, Silicon Carbide Solid State Relays onto the market. The SiC technology means a reduction in leakage current across the MOSFET and reduces the overall heat dissipation of the switch. Ideal for applications heat could be considered an issue. These switches have been designed with applications such as primary/secondary power systems in aviation and marine systems as well as DC-DC buck/boost converters where reliability and high performance are critical.

RF121 & GRF121, SPDT DC-12GHz & DC-16GHz Electro-Mechanical Relay

March, 2016. Cumbernauld, Scotland

Teledyne Relays are delighted to introduce two brand new ultra-miniature electro-mechanical relays to our product line; the RF121 and the surface-mountable GRF121 with ground shield and surface mount butt leads. These new relays boast a range of characteristics which completely supersede our previous releases.

Specs:
RF121 Frequency Range: DC-12GHz
GRF121 Frequency Range: DC-16GHz
Form: SPDT
Contact Load Rating: Resistive- 0.25A @ 28Vdc
Contact Life Rating: 3M Cycles at low level
Switching Time: 7ms max
Actuation Voltage(s): 5Vdc, 12Vdc
Lead Coating: Gold, Solder Dipped and RoHS Compliant

These relays have been designed to provide a practical standard and surface mount switching solution with RF Performance and repeatability. The RF121/GRF121 improves on Teledyne Relays’ heritage of miniature RF relays by incorporating precision transmission line structure in the internal construction of the contact system. The GRF121 relays feature a unique ground shield to facilitate surface mounting and to extend the frequency range when compared to through-hole solutions.

Both of these relays boast:
High Repeatability
Wide Bandwidth Performance
Higher Isolation between each control and signal paths
High Resistance to ESD
Operating Temp of -55C to +85C and can be stored as high as +125C

Due to the excellent high frequency handling capabilities of this switch, design engineers looking to design systems which previously used coaxial switches can now look to minimise these designs with the use of the RF121 and the GRF121. This mean smaller systems with the same, if not better, performance.

Applications Information
These relays are designed for use in the following technologies
• RF Attenuators
• RF Switch Matrices
• High Frequency Spread Spectrum Radios
• ATE
• Any system where dependable high frequency signal fidelity and performance up to 16GHz, 40Gbps is desired.

Teledyne Relays - Silicon Carbide MOSFET Solid State Relays

Teledyne Relays – Silicon Carbide MOSFET Solid State Relays

Teledyne Relays – March, 2016. Cumbernauld, Scotland

Teledyne Relays are delighted to announce our latest Hermetically Sealed Solid State Relay; the LD00KM, which incorporates the latest technology; Silicon Carbide (SiC) Power MOSFET’s. This switch is able to operate with loads up to 270Vdc, 10A. The SiC in the MOSFET means that this device will not heat up anywhere near as close to traditional Silicon MOSFETs; especially when driven near full load! This is the product of a low On-resistance, 0.042Ω for this device (At Ambient Temperatures). This means smaller heatsinking and reduced cooling requirements.

This relay also boasts optical isolation between control and load circuits to ensure that the high voltage load does not interfere with the low voltage control system, and vice versa. This is also a great protection system. This device also features fully floating power FET technology meaning that the load can be connected to either of the output terminals.

Some of the other benefits of SiC SSR’s are the reduced noise characteristics compared to traditional Si MOSFET’s and also give the device a benefit over IGBT. Another is that the SiC MOSFET show lower gate voltage swing and gate charge than comparable Silicon equivalents.

Teledyne also have a view to create a higher current handling version of this relay, the LD00KQ which will boast load handling characteristics at 270VDC @ 20A.

These devices are critical where a low ON temperature is desired and have a variety of possible applications:

-Primary & Secondary Power Systems in Commercial/Civil/Military Aircraft
-Shipboard Power Systems
-High Voltage DC/DC Converters
-Pulsed Power Applications
-High Inductance Loads

FEATURES
– High Voltage
– TTL and CMOS compatible control
– Fast switching speed
– Low profile hermetic package
– Meets 270 Vdc system requirements of MIL-STD-704
– Built and tested to the requirements of MIL-PRF-28750
