ADF5709 - MMIC VCO

📥 Download Datasheet

General Description

The ADF5709 wideband, monolithic microwave integrated circuit (MMIC), voltage controlled oscillator (VCO) supports an output frequency (fOUT) range of 9.85 GHz to 20.5 GHz while maintaining −83 dBc/Hz phase noise at 100 kHz offset without subharmonic tones.

The wide frequency tuning range and low phase noise allow phase-locked loop (PLL) solutions for a variety of frequency bands and limit the need for multiple narrow-band VCOs.

The broad frequency coverage reduces the board design complexity and simplifies the bill of materials when designing RF and microwave applications.
