HMC204C8TR

Overview

The HMC204C8TR is a passive miniature frequency doubler in a non-hermetic surface mount package. It operates within an input frequency range of 4 GHz to 8 GHz. The device utilizes GaAs Schottky diode/balun technology, requiring no DC bias. Typical conversion loss is 16 dB at the output frequency. Suppression of undesired fundamental and higher-order harmonics is typically 40 dB with respect to the input signal level. The component features small size and adds no measurable phase noise to the multiplied signal.

Feature Summary

• Passive operation without DC bias requirements
• Suppression of undesired fundamental and higher-order harmonics
• No measurable additive phase noise onto the multiplied signal
• Utilization of GaAs Schottky diode and balun technology

Applications

• Wireless Local Loop systems
• LMDS applications
• VSAT communications
• Point-to-Point Radios
• Test Equipment

Procurement Notes

Verify the specific suffix C8 for the ceramic surface mount package configuration. Confirm that the TR designation indicates tape and reel packaging if required for automated assembly processes. Check current availability status as this component may be subject to limited supply or obsolescence notices from Analog Devices Inc. Ensure compatibility with existing RF circuit designs regarding impedance matching and drive levels.

Selection Notes

Select this component when a passive frequency doubling solution is required for the 4 GHz to 8 GHz input range. Consider its suitability for applications demanding minimal phase noise addition and high harmonic suppression. Evaluate the need for a compact, non-hermetic surface mount package. Verify that the system can provide the necessary +10 dBm drive level for optimal performance specifications.
