Circuit Note CN0147 - Powering a Fractional-N Voltage Controlled Oscillator (VCO) with Low Noise LDO Regulators for Reduced Phase Noise



This circuit uses low noise, low dropout (LDO) linear regulators to supply power to a wideband integrated PLL and VCO. Wideband voltage controlled oscillators (VCOs) may have increased sensitivity to power supply noise, hence, ultralow noise regulators are recommended for best performance.

The evaluation board, which uses the ADP150 LDOs to power the ADF4350. The ADP150 represents the industry’s lowest noise LDO in the smallest package at the lowest cost.
