Miniature Surface Mount Attenuators operate up to 18 GHz.

Press Release Summary:



Housed in 2 x 2 mm package, YAT Series is available in 1 dB increments from 0–10 dB, and with as much as 30 dB attenuation. Fixed surface mount units can handle up to 2 W while still effectively dissipating any heat generated from RF/microwave power. Operating from -40 to +85°C with 50 Ω impedance, RoHS-compliant devices serve commercial, industrial, and military applications, including cellular and wireless communications systems and radar and electronic-warfare equipment.

Surface Mount Attenuators Set Levels To 18 GHz



Mini-Circuits now offers chip-sized precision attenuators with values from 0 to 30 dB in miniature 2 mm x 2 mm packages and usable across the broad frequency range from DC to 18 GHz.



Attenuation has saved many systems and circuit designs, especially when it can be added in precise, consistent amounts. Attenuation comes in many forms and sizes, but perhaps few packages that are smaller than the new 2 x 2 mm chip-sized YAT-Series fixed attenuators from Mini-Circuits. Available in 1-dB increments from 0 through 10 dB, and with as much as 30-dB attenuation packed into that tiny housing, these miniature fixed attenuators are actually fabricated with an advanced semiconductor process for consistency.



With a frequency range of DC to 18 GHz, the YAT-Series fixed surface mount attenuators can serve a wide range of commercial, industrial, and military applications, including cellular and wireless communications systems and in radar and electronic-warfare (EW) equipment. In spite of the diminutive size, the fixed attenuators can handle as much as 2 W (+33 dBm) power while still effectively dissipating any heat generated as a result of the RF/microwave power.



The YAT-Series attenuators (Fig. 1) are miniature 50-Ω passive components that can be added to a design to reduce signal levels, to increase isolation between different sections, or to improve impedance-match and return-loss performance. They are available in attenuation values through 30 dB, with minimal attenuation above and beyond their rated attenuation values.



The YAT-Series fixed attenuators all feature a maximum power rating of 2 W, a small size of 2 x 2 mm, 50-Ω characteristic impedance, and operating temperature range of -40 to +85°C. All YAT-Series fixed attenuators are RoHS compliant. They have electrostatic-discharge (ESD) ratings of 250 V, Class 1A, per the human body model (HBM) and 200 V, Class B, per the machine model (MM). The miniature fixed attenuators can be supplied in quantities as small as 20 per reel or as large as 2000 per reel, on 7-in. reels for use with automated pick-and-place assembly equipment. All YAT-Series attenuators meet the applicable requirements of MIL-STD-202, MIL-STD-750, and MIL-STD-883 for hermeticity, acceleration, vibration, mechanical shock, and temperature cycling.
