At EMV 2019, TMD Technologies Ltd. will once again be demonstrating its proven capability in the EMC/EMI field to a wide spectrum of professionals attending from industry, commerce, defence and science.

Following the showcasing of TMD’s intelligent, modular PTCM Series TWT (Travelling Wave Tube) instrumentation amplifiers last year, at EMV this year TMD will be focusing on a new ultra high power, dual combined version of the amplifier.

TMD has years of experience in power combining techniques to achieve the higher powers required for the more challenging EMC HIRF (High Intensity RF) testing applications. This has now enabled the company to offer power combined amplifiers in its advanced PTCM range – with all the standard built-in user benefits, including rugged modular design, advanced self-diagnosis, graphical user interface, and remote management.

Designed for the most demanding EMC HIRF testing applications, TMD’s new Dual PTCM units deliver more than 10 kW pulsed and greater than 4 kW CW, mainly covering the range 2-18 GHz. The exceptional performance is achieved by combining two TWTs and high voltage power supplies within one rack mountable amplifier – thus maintaining a single input and output.

TMD’s total capability is exemplified by the recently introduced PTCM Series of intelligent, modular TWT based RF instrumentation amplifiers.

“This innovative product has everything”, said Imad Gharib, TMD’s Sales Manager, RF and Microwave Amplifiers, “offering the highest performance and a wealth of operational benefits in a compact package. It suitable for not only EMC/EMI but for many scientific, medical and other applications.”

The standard PTCM Series units operate over a frequency range from DC to 40 GHz with a power output up to 50 kW. Of customisable 6U high rack mounting construction, they are designed to deliver the highest field strengths in the test environment. The user benefits provided by these highly intelligent amplifiers include self-test, fault diagnosis, modular plug and play replaceable printed circuit boards, Ethernet remote control and monitoring, and VSWR reflected power protection. A ‘system-on-chip’ (SOC) controls and synchronises all power conversion circuitry in real time, including all the monitoring, control, data logging and user interface functionality.

Furthermore, the modular 6U system allows several configuration options according to customers’ requirements.

Built to demanding military standards, with excellent thermal management, the PTCM Series amplifiers provide the highest MTBF.

Customised units and turnkey systems

Not only does TMD offer a full range of microwave products for EMC/EMI applications but, as part of its comprehensive support portfolio, it can supply customised units to customers’ own specifications, as well as providing full turnkey systems.
