HMC384LP4TR

Overview

The HMC384LP4TR is a Voltage Controlled Oscillator (VCO) from Analog Devices, designed for surface-mount applications. It operates within a frequency range of 2.05 GHz to 2.25 GHz and includes an integrated buffer amplifier. The device requires a supply voltage between 2.75 V and 3.25 V, drawing a typical current of 41 mA. Output power is specified at 3.5 dBm, with a tuning voltage range of 0 VDC to 10 VDC. Phase noise is rated at -112 dBc/Hz, and the push rate is 5 MHz/V. It is housed in a QFN-24 package measuring 4.1 mm by 4.1 mm with a height of 1 mm, suitable for operation between -40°C and +85°C.
