The HMC188MS8TR is a passive frequency doubler designed for VSAT applications, operating within the 1.25 GHz to 3.0 GHz input frequency range. Manufactured by Analog Devices Inc., this component utilizes a silicon process and is housed in an 8-lead MSOP plastic package. It functions as a signal conditioning device intended to suppress undesired fundamental and higher-order harmonics. The part is currently obsolete and no longer in production.
This component is officially classified as obsolete and has been discontinued by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Direct procurement from Analog Devices is not possible. Users must confirm the authenticity and condition of any available units through verified supply chain channels before acquisition.
Designers requiring active frequency doubling in the 1.25 GHz to 3.0 GHz range should evaluate current alternatives due to the obsolescence of this specific part. Selection criteria should prioritize compatible frequency ranges, package compatibility, and harmonic suppression performance. Consulting official replacement lists or similar active product lines is recommended to ensure long-term supply stability and design continuity.
The HMC188 series represents miniature frequency doublers developed for high-performance RF applications. The MS8 variant specifically denotes the 8-lead MSOP package configuration. This component belongs to the broader category of signal conditioning integrated circuits used in wireless communication infrastructure, particularly where compact form factors and efficient harmonic management are critical requirements.
