Established in 1990, dB Control Corp. supplies mission-critical (often sole-source) products worldwide to military organizations, as well as to major defense contractors and commercial manufacturers. The company designs and manufactures reliable high-power TWT Amplifiers (TWTAs), microwave power modules (MPMs), transmitters and power supplies with modulators. These products are used for a wide variety of applications – including radar (multimode, pulse Doppler and SAR), electronic countermeasures (ECM), electronic warfare (EW) threat simulation, airborne data links, high data-rate digital communications, test and measurement (RFI and EMC), commercial X-ray, antenna pattern and radar cross-section measurement. The company is AS9100D and ISO 9001:2015 certified.
dB Control also offers specialized contract manufacturing and repair depot services from its modern 40,000-square-foot facilities in Fremont, California. In 2019, dB Control acquired TTT-Cubed. This acquisition adds the following to the company’s product offerings: Instantaneous Frequency Measurement Units (IFM), Frequency Locked Oscillators (FLO), Digital Control Units (DCU), Antenna Control Units (ACU) and Integrated DCU’s. dB Control is a subsidiary of the Electronic Technologies Group of HEICO Corp., a publicly-traded aerospace and electronics company with more than 60 subsidiaries.
The modularity of dB Control’s designs enables rapid configuration of power products for custom applications. The company can meet stringent specs and platform requirements for ground-based, shipborne or high-altitude military manned and unmanned aircraft. Here is an overview of each product available from dB Control:
TWT Amplifiers – High-power, helix and coupled-cavity TWTAs cover the 1 to 96 GHz frequency range and are available with continuous wave or pulsed power. Built to withstand harsh environmental conditions, they are suitable for shipboard, ground mobile and unpressurized airborne environments.
Microwave Power Modules – High-efficiency, conduction-cooled MPMs provide extremely dense packaging across the 2 to 46 GHz frequency band. They meet stringent SWaP requirements and are based on a modular design for easy customization. dB Control’s MPMs are available with continuous wave or pulsed power.
Power Supplies – Tightly packaged high- and lowvoltage power supplies are used in airborne, shipboard and ground-based applications. Fully qualified for mission-critical military operations, these power supplies are suitable for very low phase noise and spurious radar transmitters, SAR, multimode radars, data links and more.
FLOs – Frequency Locked Oscillators cover frequencies ranging from 2 to 36 GHz. They are capable of changing frequencies in the order of hundreds of nanoseconds and offer various modulations, such as AM, FM and PM.
IFMUs – Instantaneous Frequency Measurement units measure both frequency and power level. They can also detect pulse on pulse signals. The DIFMU is a dualchannel IFMU.
DCUs – Digital Control Units are capable of controlling a single FLO and other RF equipment. They can be controlled and set up via a network port or preprogrammed with a removable SCD card.
ACUs – Antenna Control Units can play prerecorded antenna patterns and compensate for platform movements. For example, they can compensate for tilt and roll when mounted on an aircraft.
IDCUs – Integrated DCUs combine the control and interface power of a DCU with the RF capabilities of a FLO and the capabilities of an ACU for a complete integrated system controller in a single unit.
Custom RF Sources & Receivers – RF units of different generations may have compatibility issues. dB Control analyzes these situations and builds translation units that allow older systems to communicate and interact with newer ones.
