Ask questions about ADL5240

HI Jerry,

You can check HMC742A and HMC625B if it meets your requirement.

The best way to check the cascaded performance vs. DSA Attenuation is by ADIsimRF. There are two model for ADL5240, ADL5240AMP and ADL5240DSA. You can select ADL5240DSA at different attenuation. Below is the screenshot at max attenuation. You can find the cascaded performance at below.

Hope this helps.

In every schematic in the datasheet, L1 is 470 nH.  The entire loop filter components are always the same.  On page 24, Table 8 it states….

 The bias for the amplifier comes through L1 when VCC is connected to a 5 V supply.
L1 should be high impedance for the frequency of operation while providing low
resistance for the dc current

 I would stick with the 470 nH in all cases.  Otherwise they can simulate the response in ADS.
