BIASING THE ADL9005 BY USING THE

LTM8020

The LTM8020, µModule® regulator is suitable for the ADL9005

due to its compact size and wide input voltage range of 4 V to

36 V while maintaining high efficiency and output noise below the

maximum allowable ripple of the ADL9005 due to its high power

supply modulation ratio.

The ADL9005 can be powered by using a well regulated power

source. The LTM8020 is a complete 200 mA, dc to dc, step-down

power supply that provides a single 5 V supply to VDD through a

bias tee on RBIAS. The recommended input voltage (VIN) for the

LTM8020 is from 6.5 V to 36 V to achieve a 5 V output voltage

(VOUT).

Figure 75 shows the application circuit for ADL9005 using the

LTM8020 regulator.
