HMC1166LP5E

Overview

The HMC1166LP5E is a GaAs MMIC Voltage Controlled Oscillator (VCO) from Analog Devices, designed for high-frequency applications. It operates within a frequency range of 11.41 GHz to 12.62 GHz and provides a half-frequency output spanning 5.705 GHz to 6.31 GHz. The device features a tuning voltage range of 2 VDC to 13 VDC and draws a maximum current of 270 mA. It delivers an output power of 11 ± 4 dBm at the primary frequency and 4.5 ± 4.5 dBm at the divided output. Typical phase noise is -89 dBc/Hz, with a tuning sensitivity of 5 MHz/V. The component is housed in a 32-VFQFN package with dimensions of 5.00 mm x 5.00 mm.

Feature Summary

• Dual-output architecture providing both fundamental and half-frequency signals simultaneously
• GaAs MMIC construction ensuring low phase noise performance across the operating band
• Integrated output divider circuitry eliminating external components for frequency division
• Wide tuning voltage range supporting flexible system integration

Applications

• Point-to-point microwave radio links
• Local oscillator sources for upconversion and downconversion stages
• Test and measurement instrumentation requiring stable RF references
• Satellite communication ground stations

Procurement Notes

Verify the specific suffix 'LP5E' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure that the required tuning voltage supply aligns with the 2 VDC to 13 VDC specification. Confirm thermal management requirements for the QFN-32 package under continuous operation at maximum current draw. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-chip solution for both fundamental and divided frequencies is required to minimize board space. Consider the 11 dBm output power for direct driving of subsequent stages without additional amplification. Evaluate the -89 dBc/Hz phase noise against system jitter requirements. Compare against the broader HMC116x series if different frequency bands or packaging options are needed.

Part Context

The HMC1166 belongs to the HMC116x family of MMIC VCOs, which offer ultra-low phase noise and broad frequency coverage from 8 GHz to 14 GHz. These devices integrate the VCO core and output dividers into a single GaAs die. The LP5E designation indicates a specific lead-free, halogen-free package variant compliant with environmental standards, suitable for surface-mount assembly in high-reliability RF systems.

Replacement Considerations

Public confirmed substitute part numbers: HMC1166LP5ETR (tape and reel version), HMC1160LP5E (different frequency range).
