Overview
The HMC5128LP5E is a Voltage Controlled Oscillator (VCO) from Analog Devices Inc., housed in a QFN-32 package. It operates across three distinct frequency bands: 2.4–2.7 GHz, 4.8–5.4 GHz, and 9.6–10.8 GHz, with center frequencies of 2.55 GHz, 5.1 GHz, and 10.2 GHz respectively. The device requires a supply voltage of 5 V and supports a tuning voltage range of 2 V to 13 V. Key electrical specifications include a maximum current consumption of 370 mA and a typical second harmonic suppression of 30 dBc.
Feature Summary
- Supports triple-band operation covering low, mid, and high microwave frequency ranges within a single component
- Integrates wide tuning voltage capability for flexible frequency synthesis control
- Designed for surface-mount assembly to facilitate compact RF circuit integration
Applications
- Microwave communication systems requiring multi-band signal generation
- Test and measurement equipment needing versatile frequency sources
- Radar systems utilizing multiple operating frequency bands
Procurement Notes
Verify the specific datasheet revision and pinout configuration before integration, as manufacturing updates may occur. Confirm that the 5V supply and 2-13V tuning voltage requirements align with your system's power management architecture. Ensure thermal dissipation capabilities are sufficient for the 370 mA current draw during continuous operation.
Selection Notes
Select this component when a single VCO solution is preferred over multiple discrete oscillators to save board space. Consider the trade-off between the wider tuning range and potential phase noise performance compared to narrowband alternatives. Evaluate the QFN-32 footprint against available PCB real estate and thermal pad requirements.
Part Context
This part belongs to the HMC512 series of VCOs, which are designed for general-purpose RF applications. It shares the same QFN-32 packaging format as other devices in the family, such as the HMC512 and HMC511, ensuring mechanical compatibility while offering broader frequency coverage through its tri-band design.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. For equivalent functionality, consider the HMC512LP5E or HMC511LP5E if single-band operation suffices, though frequency ranges will differ.
