HMC736LP4E

Overview

The HMC736LP4E is an MMIC Voltage Controlled Oscillator (VCO) from Analog Devices, operating in the 14.5 GHz to 15 GHz frequency range. It utilizes HBT technology and features dual outputs, including a standard output and a divide-by-2 signal. The device requires a supply voltage between 4.75 V and 5.25 V with a current rating of 180 mA. Tuning is achieved via a voltage range of 1 VDC to 13 VDC, providing a tuning sensitivity of 24 MHz/V. It exhibits phase noise of -105 dBc/Hz and operates within a temperature range of -40°C to +85°C. The component is housed in a compact 24-QFN package measuring 4.1 mm x 4.1 mm.

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the specific lot code matches current manufacturing standards. Check for any product change notifications (PCN) regarding pinout or electrical characteristics. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Validate that the supplier provides traceable documentation for quality assurance purposes.

Selection Notes

Select this component when a fixed frequency range around 14.5-15 GHz is required without external tuning complexity. Consider the dual-output capability if both fundamental and divided signals are needed simultaneously. Evaluate power consumption constraints against the 180 mA rating. Ensure the control circuitry can support the 1-13 VDC tuning voltage range. Verify thermal management capabilities for operation up to +85°C.
