M/A-COM Technology Solutions Announces New GaN HEMT Pulsed Power Transistor

M/A-COM Technology Solutions Inc. (M/A- COM Tech), a leading supplier of high performance analog semiconductor solutions, introduced today a highly efficient 40 W pulsed power transistor optimized for civilian and military pulsed radar applications between 2.7 and 3.5 GHz.

The MAGX-002735-040L00 is a gold metalized, internally matched, GaN on SiC, RF power transistor that exhibits excellent performance when operated at +50 V, class AB operation, 40 W peak output, using a 300 µs pulse and 10% duty cycle pulsed signal. Leveraging state of the art wafer fabrication processes, the transistor provides high gain, efficiency, bandwidth, and ruggedness over a wide bandwidth for today’s demanding needs.

Based on extensive HTOL RF accelerated life testing, quantifiable test results demonstrate this high performance product is designed to provide an MTTF of 600 years or better.

“The 800 MHz of instantaneous bandwidth and rugged performance makes this versatile device an excellent choice as a driver stage or output stage for any s-band radar power amplifier application,” said Gary Lopes, Senior Director for RF Power Technologies.

Manufactured in a thermally enhanced, Cu/Mo/Cu, flanged ceramic package, the MAGX-002735-040L00 boasts excellent thermal performance as well as high breakdown voltages that allow for reliable and stable operation in extreme mismatched load conditions. Operating at +50 V, class AB, the pulsed power transistor provides 40 W of peak power at 55% drain efficiency with a minimum gain of 10.5 dB across the full 2.7 to 3.5 GHz frequency band.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
