HMC1161LP5E

Overview

The HMC1161LP5E is a monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) from Analog Devices Inc. It operates in the frequency range of 8.71 GHz to 9.55 GHz, with an integrated half-frequency output spanning 4.355 GHz to 4.775 GHz. The device features a tuning voltage range of 2 VDC to 13 VDC and a typical push of 2 MHz/V. It delivers an output power of 11 dBm at the fundamental frequency and 4 dBm at the half frequency, with a secondary harmonic level of 20 dBc. The component requires a supply voltage between 4.75 V and 5.5 V, draws a current of 300 mA, and exhibits phase noise of -90 dBc/Hz. It is housed in a 32-lead QFN package measuring 5 mm x 5 mm x 1 mm.

Feature Summary

• Integrates resonator and negative resistance amplifier for stable oscillation
• Provides dual outputs including fundamental and divided half-frequency signals
• Designed for high-performance VSAT communication applications

Applications

• VSAT uplink transmitters
• Point-to-point microwave radio systems
• Satellite communication equipment

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant, as the LP5E designation corresponds to the 32-LFCSP/QFN form factor. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure compatibility with the 2 VDC to 13 VDC tuning voltage requirements for your control circuitry. Check moisture sensitivity levels and storage conditions if the component has been held in non-climate-controlled environments prior to assembly.

Selection Notes

Select this component when a compact MMIC solution is needed for Ku-band or Ka-band frequencies with integrated frequency division. Consider the 300 mA current consumption and 5.5 V maximum supply voltage when designing the power management section. Evaluate the -90 dBc/Hz phase noise specification against system link budget requirements. The dual-output capability eliminates the need for external dividers, simplifying the RF front-end design for satellite uplink modules.

Part Context

The HMC1161 belongs to a series of MMIC VCOs designed by Analog Devices for high-frequency wireless communications. These devices typically integrate passive components and active circuits on a single die to minimize size and improve performance consistency. The HMC1161 specifically targets applications requiring precise frequency synthesis with low phase noise, serving as a key building block in modern satellite ground stations and fixed wireless access infrastructure.
