A new family of VCO products from M/A-COM Tech
The indium gallium phosphide VCOs deliver low phase noise, a wide tuning range and low current consumption.
M/A-COM Technology Solutions is launching a new set of voltage controlled oscillators (VCOs) for radio applications. The VCOs are ideal 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 optimising for low phase noise, wide tuning range, and low current consumption.

Production quantities and samples of MAOC- 009871, MAOC-009872, and MAOC-010344 are available from stock and further details are available from M/A-COM’s website.

RF SP3T switch for Wi-Fi, Bluetooth & applications up to 6GHz
Low insertion loss and small package size of the gallium arsenide MMIC switch enable combo wireless designs at frequencies from 0.5 to 6.0 GHz.
“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 also 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.
