Electronic component maker KYOCERA AVX has released the CP2816 series of integrated thin-film (ITF) high-directivity couplers for high-frequency wireless systems.  

The couplers enable quick adjustments to RF parameters and are for use in high-frequency wireless applications extending throughout the telecommunications, commercial aerospace, military and automotive markets, including active antennas, basestations, emergency systems, mobile tactical radios, VHF and UHF radios, radar systems, and test equipment.

Developed in response to user requests for small, high-power couplers compatible with VHF and UHF bands, the couplers have a rugged, compact and low-profile 2816 (7 by 4mm) case and exhibit 20W continuous power handling, 50Ω impedance and high-frequency performance from 225 to 750MHz and -40 to +105˚C.

They also exhibit a tight coupling factor over the frequency range (-10±1.2dB, -10±2dB, -15±2dB and -15±4dB), low insertion loss extending from less than -0.8dB to less than -0.9dB, voltage standing wave ratio (VSWR) of 1.3, and -14dB directivity. Additional benefits include high temperature stability, high lot-to-lot and part-to-part reliability, and repeatable RF performance.

“Our new CP2816 series integrated thin-film high-directivity couplers satisfy growing market demand for small, high-power components optimised for microwave and RF systems,” said Mohammed Abu-Naim, RF product manager at KYOCERA AVX. “RF engineers are being challenged to design smaller, higher-power and more densely populated circuits, and the new CP2816 couplers ensure that the transmitted power meets the specification in applications like these and prevent the power amplifiers from burning out due to return power.”

The couplers (www.kyocera-avx.com/products/rfmicrowave/couplers/high-directivity-couplers/high-directivity-couplers-cp2816) have nickel land grid array (LGA) terminations equipped with a lead-free solder coating that’s compatible with automated or manual soldering processes include reflow, wave and vapour phase. They’re also RoHS compliant, compatible with IATF 16949, manufactured in an ISO-9001 facility, and packaged on tape and reel for reliable assembly.  

KYOCERA AVX (www.kyocera-avx.com) designs, develops, manufactures and supplies capacitors, antennas, interconnects, circuit protection and timing devices, sensors, controls, filters, fuses, diodes, resistors, couplers, and inductors for use in the international 5G, IoT, aerospace, automotive, consumer electronics, industrial, medical and military markets.
