High power dual combined modular instrumentation amplifier

Imad Gharib, TMD’s Sales Manager for Instrumentation Amplifiers stated: “We have years of experience in power combining techniques used in our previous classic designs, to achieve the higher powers required for the more challenging EMC HIRF (High Intensity RF) testing applications. This has now enabled us to offer power combined amplifiers in our newest PTCM range, with all the built-in user benefits, including rugged modular design, advanced self-diagnosis, graphical user interface, and remote management. Our project teams are on schedule, and development of the PTCM high power dual version is now advanced enough for us to take orders.”

Typically, the new dual PTCM units deliver more than 10kW pulsed and greater than 4kW CW, mainly covering the range 2-18GHz. 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.

The inherent high level of amplifier intelligence is provided by a state of the art system, controlling and synchronising all power conversion circuitry in real time, and all the monitoring, control, data logging and user interface functionality.

The high reliability PTCM amplifier is built to demanding military standards, with excellent thermal management to provide outstanding MTBF. Also featured is VSWR (Voltage Standing Wave Ratio) reflected power protection.

In addition to the HIRF EMC/EMI application, the PTCM dual can be used in scientific, medical and other fields.
