HMC1168LP5E

Overview

The HMC1168LP5E is a GaAs MMIC Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc. It operates in the 12.47 GHz to 13.72 GHz frequency range with a half-frequency output at 6.235 GHz to 6.86 GHz. The device utilizes a QFN-32 package and requires a supply voltage between 4.75 V and 5.5 V. Key electrical parameters include a tuning voltage range of 2 VDC to 13 VDC, a typical phase noise of -85 dBc/Hz, and an output power of 10 dBm. Maximum current consumption is rated at 240 mA, with a tuning sensitivity of 2 MHz/V.

Feature Summary

• Integrates a free-running voltage-controlled frequency source within a compact monolithic microwave integrated circuit structure.
• Provides dual output capability with fundamental frequency generation and a dedicated half-frequency signal path.
• Utilizes Gallium Arsenide technology to achieve stable oscillation across specified temperature ranges.

Applications

• High-frequency radar systems requiring precise local oscillator signals
• Satellite communication transceivers operating in Ku-band frequencies
• Test and measurement equipment needing low-phase-noise reference sources

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Ensure handling procedures adhere to electrostatic discharge precautions for sensitive semiconductor devices. Cross-reference datasheet revision A specifications against procurement documentation to guarantee parameter consistency.

Selection Notes

Select this component when designing circuits requiring a specific 12.47 GHz to 13.72 GHz output with simultaneous half-frequency availability. Evaluate thermal management requirements given the 240 mA current draw and QFN-32 package constraints. Ensure control voltage supplies support the 2 VDC to 13 VDC tuning range without exceeding maximum ratings. Consider PCB layout guidelines for RF ground connections to maintain performance integrity.

Part Context

This part belongs to the HMC1168 series of MMIC VCOs designed for high-performance RF applications. It shares architectural similarities with related models like the HMC1167 but differs in center frequency and output characteristics. The LP5E suffix indicates a specific lead-free packaging variant compliant with environmental standards. It serves as a specialized solution for engineers needing integrated frequency synthesis without external resonators.
