HMC506LP4

Overview

The HMC506LP4 is a Voltage Controlled Oscillator (VCO) from Analog Devices, designed for VSAT radio applications. It operates within a frequency range of 7.8 GHz to 8.7 GHz. The device requires a supply voltage between 2.75 V and 3.25 V, with a typical operating voltage of 3 V. It draws approximately 77 mA to 88 mA of current. The output power is rated at 14 dBm. Phase noise performance is specified at -103 dBc/Hz. The tuning voltage range extends from 1 VDC to 11 VDC, providing a push of 78 MHz/V. The component is housed in a QFN-24 package measuring 4.1 mm by 4.1 mm with a height of 1 mm. It supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct package type and tape/reel specifications. Confirm that the required frequency range and phase noise metrics align with system requirements before finalizing the purchase order. Check for any recent product change notifications or end-of-life announcements from Analog Devices to mitigate supply chain risks.

Selection Notes

Select this component when a high-output power VCO is required for Ku-band applications. Ensure the design accommodates the 3 V supply rail and the associated current consumption. Verify that the PCB layout supports the QFN-24 thermal pad requirements for adequate heat dissipation. Consider the tuning linearity and phase noise specifications relative to the local oscillator requirements of the target receiver or transmitter architecture.

Part Context

The HMC506LP4 belongs to the HMC506 series of monolithic microwave integrated circuits. It is manufactured by Analog Devices Inc., formerly Hittite Microwave Corporation. This part is specifically optimized for satellite communication frequencies. It represents a solution for compact, high-performance oscillators in space-constrained RF modules.

Replacement Considerations

Check for the HMC506LP4ETR variant, which offers different packaging options such as cut tape or reel. Evaluate other members of the HMC50x series if frequency adjustments are needed. Consult Analog Devices for cross-reference recommendations based on updated inventory status.
