Comb Generator Portfolio Delivers Industry-Leading Phase Noise Performance


MLPNC Series comb generators provide superior phase noise performance up to 20 dBc/Hz better than conventional SRD-based solutions

Lowell, Massachusetts–MACOM Technology Solutions Inc. (“MACOM”) announced a portfolio of Non-Linear Transmission Line (NLTL) comb generators optimized to meet the demanding performance requirements of radar transceiver, VSAT and microwave radio applications. Featuring the lowest phase noise in the industry today, MACOM’s MLPNC Series comb generators deliver superior performance and ease-of-design compared to conventional step recovery diode (SRD) based offerings.

The industry-leading phase noise performance delivered by MACOM’s MLPNC Series comb generators is expected to significantly improve the overall performance of RF multiplier modules, complemented by a variable low input power profile (18 – 24 dBm) that relaxes the power requirements on power amplifiers and reduces overall power consumption. MLPNC Series comb generators also enable higher harmonic power at higher frequencies, in contrast with SRD-based comb generators whereby output power rapidly rolls off above 20 GHz.

MACOM’s monolithic, NLTL-based MLPNC Series comb generators reduce design complexities by eliminating the harmonic generation circuitry needed with SRD-based devices. No bias or tuning is required, and the wide input frequency range extends from 75 – 1500 MHz across the portfolio, enabling the use of a single comb generator for multiple designs, or in combination with a tunable source. MACOM’s MLPNC Series comb generators are available in space saving, compact SMT and connectorized SMA packaging options.

“With the launch of our MLPNC Series comb generators, MACOM has again pushed the boundaries of RF device performance while simultaneously helping to simplify our customers’ frequency synthesizer designs,” said Graham Board, Senior Director of Product Marketing, MACOM. “We believe that our NLTL comb generators deliver best-in-class phase noise performance with useable harmonics up to 50GHz. MACOM’s Combs are MMIC-based so they are more reliable and repeatable than SRD based solutions. As a further advantage we offer both surface-mount and connectorized solutions.” 

MACOM's MLPNC Series comb generators are available to customers today.
