LMX2572: LMX2572 external pull up for increased output power

Part Number: LMX2572
Other Parts Discussed in Thread: LMX2592, , LMX2582

Hello,

Does the LMX2572 support external pull up resistor, inductor or a tranformer for increased output power like LMX2582 and LMX2592?

All the best

In addition can the LMX2572 be used as a drop in replacement for LMX2582 with the same schematic? Meaning, can the LMX2572 use the same example schematic as the LMX2582 has in its datasheet?

Hi There,

LMX2572 and LMX2582 are pin compatible, but the schematic is slightly different. For example, LMX2572 output has built-in 50Ω pull-up so external resistor/inductor pull-up is not allowed.
