HMC1165LP5E

Overview

The HMC1165LP5E is a Gallium Arsenide (GaAs) Voltage Controlled Oscillator (VCO) from Analog Devices, designed for RF/2 applications. It operates within a frequency range of 11.07 GHz to 11.62 GHz, with a secondary output at 5.535 GHz to 5.81 GHz. The device requires a supply voltage between 4.75 V and 5.5 V and draws 310 mA. It features a tuning voltage range of 2 VDC to 13 VDC and offers a sensitivity of 10 MHz/V. Output power levels are specified at 8 dBm and 5 dBm, with second harmonic suppression of 14 dBc and phase noise of -88 dBc/Hz. It is housed in a 32-lead LFCSP package measuring 5 mm x 5 mm.

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm RoHS compliance details and moisture sensitivity level prior to soldering. Ensure handling procedures meet ESD standards given the humidity-sensitive classification. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when specific Ka-band frequency generation is required with integrated division capabilities. Consider the 310 mA current draw and 5.5 V maximum supply voltage against system power budgets. Evaluate the 10 MHz/V tuning sensitivity against loop filter design requirements. Compare phase noise performance against system link budget constraints.
