TMD’s latest microwave instrumentation amplifiers meet the stringent demands of HIRF EMC testing for commercial aircraft

TMD Technologies Limited (TMD) has introduced six new high power, pulsed TWT (Travelling Wave Tube) instrumentation microwave amplifiers, which are optimised to meet the latest stringent demands of high intensity RF (HIRF) EMC testing. The amplifiers are also suitable for other applications, including scientific and laboratory research and the medical field.

Achieving the technical challenge of providing high pulsed power - even at L band - TMD’s latest PTC6000 and PTC7000 series travelling wave tube amplifiers (TWTAs) between them cover the frequency range of 1-18 GHz with minimum power outputs of 3.5 kW pulsed, up to a maximum of 14 kW pulsed in some parts of the band. This satisfies the very latest aerospace EMC (Electro Magnetic Compatibility) testing requirements for commercial aircraft such as the Airbus 380 and Boeing 787. Due to the increasing use of carbon fibre in their structures, these latest aircraft are more susceptible to microwave radiation than the older type designs employing all metal structures, hence the necessity for the most advanced and stringent test procedures.
