InGaP HBT-based VCOs with MTBF of 2,500,000 hours

M/A-COM Technology Solutions Inc. has introduced a new set of voltage-controlled oscillators (VCOs) for point-to-point radio, point to multipoint radio, communications systems, and low phase noise applications. The InGaP HBT-based VCOs are easily integrated into a phase lock loop, using a divide-by-two output. The MAOC-009871, MAOC-009872, and MAOC-010344 meet the high performance requirements of high capacity digital radios by optimizing for low phase noise, wide tuning range, and low current consumption.

"The MAOC-009871, MAOC-009872, and MAOC-010344 are expansions to M/A-COM Tech's point-to-point VCO product family. Low phase noise and low DC power consumption are key product features that are beneficial for cellular backhaul radios," said Jack Redus, Product Manager. "The full product family consists of 15 standard product VCOs covering 5.7 to 14.2 GHz. Custom frequency ranges are available upon request."

Packaged in a lead-free 5mm, 32-lead PQFN package, the VCOs feature an integrated buffer amplifier and excellent temperature stability. The package features low lead inductance and an excellent thermal path. Operating with case temperature at or below +85°C, the VCOs allows for a MTBF of 2,500,000 hours. With a 5.0 V bias supply, these VCOs operate between the 8.4 GHz to 11.8 GHz frequency band.
