HMC205

Overview

The HMC205 is a passive miniature frequency doubler implemented as a GaAs MMIC die. It operates with an input frequency range of 6 GHz to 12 GHz, producing an output at twice the input frequency. The device utilizes GaAs Schottky diode and balun technology, requiring no DC bias voltage for operation. It provides typical suppression of undesired fundamental and higher-order harmonics relative to the input signal level.

Feature Summary

• Passive operation eliminating the need for external DC bias supplies
• Integration of GaAs Schottky diode and balun technology within a miniature MMIC die
• Suppression of undesired fundamental and higher-order harmonic signals

Applications

• Wireless Local Loop systems
• LMDS, VSAT, and Point-to-Point Radios
• Test Equipment

Procurement Notes

Verify that the procurement source provides the bare MMIC die form factor, as the HMC205 is not packaged in standard surface-mount or through-hole enclosures. Confirm compatibility with specialized mounting techniques required for bare dies. Ensure documentation confirms the GaAs material composition and passive architecture matches the original specifications before integration into RF designs.

Selection Notes

Select this component when a passive frequency doubling solution is required for the 6 GHz to 12 GHz input band without adding phase noise. The absence of DC bias requirements simplifies power distribution in sensitive RF circuits. Consider the bare die format necessitates specific handling and assembly processes compared to packaged alternatives.

Part Context

Manufactured by Analog Devices Inc., formerly Hittite Microwave Corporation, the HMC205 belongs to a family of GaAs MMIC frequency multipliers. It shares underlying technology with other Hittite MMIC mixers, leveraging established Schottky diode performance characteristics for reliable harmonic generation in microwave applications.
