Microwave Components
We are the world leader in temperature variable and fixed attenuators from DC through Q band, featuring our Thermopad® line of products which compensate for gain variation over temperature. Our attenuators are available in many package styles including: chip, tab & cover, flange mounted and coaxial models.
We are one of the world’s top suppliers of high-power RF/MW terminations and resistors, including our new product option printed on CVD diamond which are excellent for use where size, frequency response and power are critical.
We are a leader in signal distribution components with our HybriX® line of products including 3 dB hybrid and directional couplers, 2-, 3- & 4-way power dividers, DC blocks & RF cross-overs.

  • Diamond RF Resistives®

    Diamond is the best thermal conductor on earth. Combined with a low dielectric constant, it is an excellent RF dielectric material for high-frequency applications in which thermal performance is equally critical. By applying cutting-edge thin film process and extensive millimeter wave design experience, EMC Technology has created a high-performance line of resistive components. The resulting products, our Diamond RF Resistives® resistors, terminations, and attenuators, are significantly reduced in size and unparalleled in average and peak power handling.
  • Fixed Attenuators

    We are the world leader in fixed attenuators from DC through Q band.  Fixed attenuators are available in 0.1 to 400 W versions, covering DC to 50 GHz applications and offered in 0 to 30dB values. Our attenuators are available in several package styles including chip, tab & cover, flange and coaxial models for use in both low and high power applications. These products are available in standard commercial product as well as high reliability versions. Features: 
    • Substrates - BeO, AlN, and Alumina
    • Commercial and High Reliability Product Lines
    • Frequency Range from DC to 50 GHz
    • Attenuation Values from 0 to 30dB
    • Space and Military Qualified
    • Surface Mount, Wire-Bondable and Coaxial Configurations
    Benefits:
    • Small Footprint
    • Totally Passive
    • Power Handling up to 400 Watts
    • Several Metallization Options Available, including a RoHS compliant version
  • Resistors

    EMC Technology & Florida RF Labs offer low and high power RF resistors including surface mount chips, tab & cover chips, flange mounted and rod types. These resistors are available with Alumina, ALN, BeO and CVD substrate materials. Some devices use a tuned circuit design to minimize parasitic capacitance across their usable frequency bands. Most devices are available in a wide range of resistance values, typically from 1 ohm to 1 K ohms. Choose from a variety of metallization finishes for easy mounting to a heat sink or directly to the printed circuit board.  Typical finishes include: Lead-free, RoHS compliant plating (silver or gold), solder finish with SN63 or solder fused finish with SN63 depending upon package type. Select from bulk, tape & reel, or waffle packaging, again, depending upon resistor package style.

  • Thermopad® Temperature Variable Attenuators

    EMC Technology is the world leader in temperature variable attenuators from DC through Ka Band, featuring our patented Thermopad line of products which compensate for gain variation over temperature. The Thermopad® (Patent # 5,332,981) is a totally passive, surface mountable temperature variable attenuator. It requires no bias or control voltages and does not generate distortion. The Thermopad can be used in place of a standard chip attenuator to combine level setting or buffering and temperature compensation in a single chip design. This will reduce component count, increase reliability, and lower costs. Applications include power amplifiers, mixers, MMIC amplifiers, directional couplers and diode detectors.
    Features Benefits Applications
    Frequency Range from DC to 36 GHz Small Footprint Power Amplifiers
    Attenuation Values from 1 to 10dB Surface Mountable Military
    Wire Bondable Connections Available Zero Distortion, Totally Passive Mixers
    Negative & Positive Coefficients of Attenuation Available Power Handling up to 2 Watts Satelite Communication
