HMC204MS8G

Overview

The HMC204MS8G is a passive miniature frequency doubler implemented in an 8-lead MSOP surface mount package. It operates with an input frequency range of 4 GHz to 8 GHz, producing doubled output signals. The device utilizes GaAs Schottky diode and balun technology, requiring no DC bias voltage. Typical suppression of undesired fundamental and higher-order harmonics is 42 dB relative to the input signal level. Conversion loss is typically 17 dB at the second harmonic (Fo).

Feature Summary

• Passive operation eliminating the need for external DC bias supplies.
• High harmonic suppression of undesired fundamental and higher-order frequencies.
• Compact 8-lead MSOP surface mount packaging for space-constrained designs.
• Integration of GaAs Schottky diode and balun technology within a single MMIC die.

Applications

• Wireless Local Loop systems
• LMDS, VSAT, and Point-to-Point Radios
• UNII & HiperLAN applications
• Test Equipment

Procurement Notes

Verify component status as the HMC204MS8G is listed as obsolete and no longer manufactured by Analog Devices Inc. Confirm availability through authorized distributors or secondary markets if procurement is required. Ensure replacement components meet identical electrical specifications and pinout compatibility for existing designs.

Selection Notes

Select this component for high-frequency doubling applications requiring minimal phase noise addition and compact form factors. The passive nature simplifies power supply design by removing bias requirements. Evaluate thermal management and PCB layout constraints associated with the MSOP8 package when integrating into RF signal chains.

Part Context

The HMC204 series represents a family of passive frequency doublers from Analog Devices (formerly Hittite Microwave Corporation). These devices are designed for RF signal conditioning, leveraging established GaAs MMIC processes. The MS8G variant specifically denotes the surface-mount package configuration suitable for automated assembly.
