Greensboro, N.C.RF Micro Devices has introduced five single junction circulators for wireless infrastructure applications.
The circulator product family includes the PC0882AG-21H, PC0940AG-21H, PC1843AG-21H, PC1960AG-21H and PC2140AG-21H. Each circulator delivers optimum electrical performance and rugged construction required by the demanding operational requirements of the high power, linear amplifier and transceiver sections of cellular base stations, repeaters and other forms of transmission equipment.
The single junction circulators are manufactured with samarium cobalt (SmCo) magnets packaged in aluminum housings, providing immediate improvements in reliability and performance vs. existing generations of circulators. The PCxxxAG-21H line of single junction circulators is specifically designed to cover the five major cellular frequency bands from 869MHz to 2170MHz, while exhibiting high intermodulation distortion (IMD) performance, low insertion loss and high isolation. All of the "drop-in" single junction circulators are offered in industry standard 1-in. x 1-in. packages for ease of implementation, and all are lead-free and RoHS compliant.
Pricing: $10.58 each in quantities of 1,000 units.
Availability: Sampling with volume shipments expected in the second quarter of this year.
Datasheets: PC0882AG-21H, PC0940AG-21H, PC1843AG-21H, PC1960AG-21H and PC2140AG-21H.
