High-Performance Microwave Power Modules (MPMs) for SAR, ECM and Military Airborne Platforms

dB Control’s high-efficiency, conduction-cooled MPMs provide extremely dense packaging without sacrificing reliability or performance. Each small, lightweight package includes a:

• Highly efficient, mini-helix traveling wave tube (TWT)
• Low-noise, solid state driver amplifier
• Extremely compact, high-voltage modular power supply featuring low-noise topology and highly efficient solid state power conversion circuits

Applications

• Manned and unmanned platforms 
• High-performance radar systems
• Data links
• Electronic countermeasures (ECM)
• Satellite communications

Modular design for easy customization

Flexible packaging options are available for both continuous wave and pulsed power MPMs. For additional configurations, contact Meppalli Shandas.

The dB-4118 is extremely effective for ECM as it features a pulse repetition frequency (PRF) rate that is more than twice as high as the industry standard 100 KHz. The compact, conduction-cooled MPM uses a high-speed modulator to obtain a pulse modulation of up to 250 KHz, operates in the 6-18 GHz frequency range and provides 100W CW RF output power.

The pulsed dB-3746 is ideal for high-resolution synthetic aperture radar (SAR) and other high-performance radar applications as it features very-low phase noise and spurious, excellent amplitude and phase stability. The db-3746 operating in the 9-10 GHz frequency range, providing 1 kW peak power at 6% maximum duty cycle and +28 VDC prime power.

The dB-3758 MPM is designed for extremely low phase noise radar transmitter applications and ensures that no signal is lost by utilizing two technologies – synchronization of the power supply switching frequency with a radar system clock and blanking during the pulse. Operating in the 9-10 GHz frequency range, the X-band MPM provides 1 kW peak output power at a 6% duty cycle, while the Ku-Band MPM provides 400 W output power at a 35% duty cycle. Both MPMs are designed to withstand harsh airborne environments.

The dB-3803 high-power MPM provides complete protection for the TWT and power supply. This MPM operates from the aircraft's three-phase, 400 Hz power supply to provide 300 Watts of continuous wave power in the X- or Ku-Band. An integral EMI filter ensures compliance with MIL-STD- 461 requirements. Pulsed operation is available as an option. The dB-4112, a compact version of the dB-3803, operates in the 6-18 GHz frequency range, providing 100 W continuous wave or pulsed power with 270 VDC prime power.
