TMD will be exhibiting a wide range of travelling wave tube amplifiers (TWTAs) on Stand 49 at EMC 2015 – incorporating significant technical features to cover a gamut of applications in the EMC, scientific and medical fields, as well as in passive intermodulation (PIM) testing, telecommunications and EW simulation.

TMD’s latest amplifiers on show are proven in the field, and are achieving generally over 10 kW of power and up to 40 kW for certain pulsed models, with a frequency range up to 40 GHz using suites of both TWT based and solid state amplifiers.

The popular PTC Series ultra-high power pulsed TWTAs has now been further extended, optimised for use in HIRF EMC testing. Using the PTC Series instrumentation amplifiers, EMC test laboratories have generated 14,000 V/m (measured in an anechoic chamber), easily complying with the latest, most demanding RTCA/DO-160 G and L test requirements. Other standards covered include: MIL Standard, EUROCAE and AIRBUS ABD 100.

In keeping with its philosophy of offering customers the advantages of both tube and solid state technology TMD has also introduced a full range of solid state amplifiers, operating below 6 GHz and designated the PTCS Series.

“Our amplifiers offer highest reliability, compact and lightweight design and the ability to customise for special applications”, said TMD’s technical sales representative, Imad Gharib. “Moreover, we are able to provide full turnkey EMC testing systems, and have close contact with both antenna specialists and anechoic chamber specialists to achieve this.”
