Millimeter Wave Products

Ducommun serves the avionics, communications, defense, industrial, intelligent traffic systems, medical, and test equipment markets with millimeter wave products. They design and manufacture products including amplifiers, antennas (horn and patch), mixers, oscillators, multipliers, radar sensors, industrial grade phase shifters, lab components, up/down-converters, along with sub-systems and integrated Assemblies.

Amplifiers

Ducommun offers Low Noise (ALN), High Power (AHP), Full Waveguide Band (AFB) and General Purpose (AGP) amplifiers to cover the frequency range from 18 to 96 GHz. These amplifiers utilize thin-film and microelectronics manufacturing techniques and are discrete and/or MMIC PHEMT devices based. These amplifiers feature low noise, high output power, single DC power supply and wide operation temperature range. The amplifiers are offered in two categories, standard and custom-built. Both standard and custom-built amplifiers are equipped with various RF interface, including standard waveguide or coaxial connector for convenient system integration. The optional input and output integrated isolators are available as an option to further improve the port return loss.

Antennas

Ducommun millimeter wave products include ACH, ARH and ALC series circular, rectangular gain horn antennas and lens corrected horn antennas for system applications. Low side lobes, ridged configuration and low cost are the main features of these antennas. The standard gain value and half power beamwidth at mid-frequency point of each waveguide band are 23 dBi and 9 degrees, respectively. Other gain values are available as customer order. These antennas cover the frequency range of 18 to 110 GHz.

Ducommun also offers GPS antenna (AGA) for GPS system applications. The antenna is constructed with machined housing, ceramic patch array, low noise amplifier, filter and high performance Radome material.

Frequency Converters

Ducommun’s frequency converter families include waveguide detectors (FAS), passive and active multipliers (FMP and FMA), up and down converters (FUB and FDB), harmonic mixers (FDH), subharmonically pumped up and down converters (FUS and FDS) and phase detectors and single sideband modulators (FPB and FSS). These devices are offered in 7 waveguide bands to cover entire 18 to 110 GHz frequency spectrum. These converters employ high performance GaAs Schottky beamlead diodes and DLT’s proprietary circuit configuration to produce superior performance, such as low conversion loss and up to full waveguide instantaneous operation bandwidth.

Oscillators

Ducommun’s oscillator family includes FET based dielectric resonator oscillators (OFD), phase locked oscillators (OPL), Gunn diode based low cost Gunn oscillators (OGL), bias tuned Gunn oscillators (OGB), mechanically tuned oscillators (OGM), varactor tuned Gunn oscillators (OGV), injection locked Gunn oscillators (OGI) and Gunn oscillator bias regulators and modulators (OGR and OMR). In the mechanically tuned Gunn oscillator family, the ultra broadband series (OGF) delivers up to full waveguide tuning bandwidth.

Ducommun is the industry leader of design and manufacturing high performance Gunn diode oscillators. Combined with proprietary cavity design technology and experience, Ducommun’s Gunn oscillators deliver state-of-the-art performance in the industry. In addition, Ducommun has delivered more than 20,000 high performance Gunn oscillators since March 2001.

Ferrite Devices

Ducommun’s products include very broad ferrite device selections to cover 100 MHz to 110 GHz operation frequency range. These devices include narrow band drop-in (FID and FCD), connectorized (FIC and FCC), junction (FIW and FCW) isolators and circulators and iso-adapters (FII and FCI). The broad bandwidth versions are offered as full band junction isolators and circulators (FIF and FCF) and Faraday isolators (FFF). These devices feature low insertion loss, high isolation and wide operating temperature range. Low cost and volume production versions of these ferrite devices are available per customers’ request.

Passive Components

Ducommun millimeter wave products include various passive components including multi-hole directional couplers (PCM), crossguide couplers (PCC), magic tees (PCT), coax power dividers (PPD), bandpass, low pass and high pass filters (PFB, PFL and PFH), waveguide diplexers (PDC), waveguide transitions (PRC and PTW), waveguide to coax adapters (PTC) and waveguide components (PWS, PWE, PWH, PWM and PWT). These passive components cover frequency range from 8.2 to 110 GHz and feature high performance and low cost.

Sub-Systems

Ducommun millimeter wave sub-system products include standard and custom-built modules or sub-assemblies.

Ducommun’s self-contained, in-house components design and fabrication capacities ensure the breadth of sub-assemblies offered from rapid prototyping and proof of concept to full production. Ducommun has produced many high performance millimeterwave band sub-assemblies for commercial and military system applications. Among them, the K and Ka band directional Doppler Radar front ends are in production. Several hundreds of sets have been delivered. In addition, Ducommun has delivered Ka through W band engineering prototypes for plasma detection system, automotive Radar, speed Radar, automatic test set, radio telescope, missile terminal guidance, telecommunication system etc. applications.
