New series of high-directivity couplers launched

Kyocera AVX has released its new CP2816 Series of integrated thin film (ITF) high-directivity couplers for high-frequency wireless systems. 

Developed in response to customer requests for small, high-power couplers compatible with very and ultra-high-frequency (VHF and UHF) bands, the new series ITF high-directivity couplers feature a rugged, compact, and low-profile 2816 (7mm x 4mm) case and exhibit 20W continuous power handling, 50Ω impedance, and exceptional high-frequency performance from 225–750MHz and -40C to +105C. They also display 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, a VSWR of 1.3 and -14dB directivity. Further benefits include high temperature stability, high lot-to-lot and part-to-part reliability, and repeatable RF performance.

The new series also allows quick adjustments to RF parameters and is ideal for use in high-frequency wireless applications extending throughout the telecommunications, commercial aerospace and defence, and automotive markets, including active antennas, base stations, emergency systems, mobile tactical radios, VHF and UHF radios, radar systems, and test equipment.

“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, Kyocera AVX. “RF engineers are being challenged to design smaller, higher-power, and more densely populated circuits, and the new CP2816 Series 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 new CP2816 Series ITF high-directivity couplers feature nickel LGA terminations equipped with a lead-free solder coating compatible with automated or manual soldering processes, including reflow, wave, and vapour phase. They are also RoHS compliant, compatible with IATF 16949, manufactured in an ISO-9001 facility, and packaged on tape and reel for reliable assembly.
