For more than 70 years, Spectrum Control has been setting the standard for reliability in mission-critical air, land, sea, and space applications. Our solutions enable critical defence platforms across NATO operations, coalition partners, and key UK/European platforms.

Spectrum Control has a strong heritage of technical prowess and manufacturing excellence built over seven decades. The company’s focus has been in two distinct areas: conditioning & processing of RF and microwave signals and protecting equipment from electromagnetic interference. These major categories have evolved to encompass adjacent technologies, including power distribution systems for high-rel applications, optical transmit/receive modules, and high-temperature electronics.

During those 70 years of successful growth and market expansion, the company has acquired or merged with synergistic companies and operating divisions to address market opportunities and to fill gaps in our product line. Today’s Spectrum Control is comprised of more than 40 businesses and product groups, the oldest of which is C-MAC, dating back to 1953.

We’re redefining RF and system integration with scalable subsystems, compact architectures, and mission-tailored assemblies that drive agility, reduce SWaP, and enable coalition-ready, forward-compatible solutions.

Rugged, Micro-Optical Transceivers

Opto 1.png

Pluggable SMT Micro-Optical Hybrid Transceiver for high-speed, reliable data transfer in harsh environments

Quad-channel transmit (TX) and receive (RX) @ 20 Mbps to 10 Gbps per channel. Innovative pluggable optical connector interface, BGA solder ball base layer contacts, for PCB mounting, and a hermetic enclosure.

Applications

Relevant applications include

  • Airborne fibre optic front ends (FOFE)
  • Direct sampling systems
  • High-speed data networks

 

High Temperature Electronics

 HIgh Temp Module.png

Our hybrid multi-chip modules (MCMs) are suitable for continuous operation at Ultra High Temperature (225°C) and under severe mechanical shock and vibration.

Spectrum Control's specialized technique using bare die on thick film ceramic interconnects overcomes the high-temperature performance and reliability limitations of traditional glass fibre laminate printed circuit boards.

Applications

Relevant applications include but are not limited to:

  • Hypersonics controls
  • Near-engine sensor networks
  • Space: launch platforms and satellites

Operating temperatures

  • Standard temperature -55°C to 150°C
  • High Temperature 150°C to 175°C
  • Extreme high temperature 175°C to 200°C
  • Ultra high temperature 200°C to 225+°C

Quad-Channel Tx/Rx Modules

Modular COTS solution for rapid development/deployment of active antenna array systems and sub-systems.

Spectrum Control’s Quad Transmit Receive Module (QTRM) is ready to use out of the box for AESA radar systems. Each module includes four transmit/receive channels, built-in control logic, monitoring, and protection features. Its modular design allows radar teams to rapidly build scalable antenna arrays, reducing integration complexity and total cost.

Key Features

  • RS485 Half-Duplex, 5.0 Mbps serial data bus for control and monitoring.
  • DSP externally programmable via JTAG
  • TX output power, HPA temperature, operating current and power supply health monitored and reported on request
  • Direction cosines used for beam steering
  • 4-bit array address code giving up to 16 QTRM sub-array (64- element array)
  • TRM’s respond to individual address or broadcast messages.

RF+ SiP mmWave Block Converters

30x30 SiP BGA.png

Miniature, modular, and intelligent building blocks for modern RF+Digital systems

High-fidelity millimeter wave block conversion in a high-volume package. Extend the frequency range of your existing 2-18 GHz system or design a new system that operates in the 18-40 GHz bands with small footprint and high performance.

SiP Platform Overview

Complete platform for mixed signal integration in small surface-mount packages: high fidelity RF signal conditioning, power supply & distribution, and digital tuning, command & control.

  • Miniature and integrated
  • Software-instrumented
  • Dramatically reduced cost and development time
  • No performance trade-offs

Ultraminiature High Q RF Filters
