Next generation X band radar MPM developed by TMD Technologies
The new features confirm the 1 kW PTX8400 as an ideal power module for high performance radar applications where space and weight are especially critical, such as in unmanned aerial vehicle (UAV) and helicopter platforms.
Electronic Warfare - Emerging Trends, Approaches, Key issues and Investment Outlook
The main enhancement is that the unit now uses a TMD ring loop travelling wave tube (TWT), which has a higher gain per unit length than a comparable helix style TWT, thus allowing additional internal space for future higher duty (10%) variants. The ring loop structure also offers a flatter bandpass characteristic and lower harmonics, both of which have reduced its noise performance.
The module also has improved built-in test electronics (BITE), which now incorporate an integrated visual display to check the health of the unit at any time.
The new PTX8400 has a high electrical efficiency and therefore low prime power consumption, operating from 28 Volts DC, and very low phase noise, which is essential for demanding radar applications. The duty ratio is 5%, with growth potential to 10% established.
