LMX2572: Single end output configuration

ttd

Part Number: LMX2572

Dear Technical Support Team,

Datasheet shows following Pout(single-end output power) specification.

1.)Does this single-end output configuration mean "Figure 169" of "8.1.5.3" or transformer converts differential output of LMK2572 to single-end?

Which configurations are evaluated for Pout(typ 4.5dBm)?

2.) Is this Pout(typ 4.5dBm) evaluated by LMX2572EVM?

This board is ac-coupled for RF output.

3.) Can each RF out "A" and "B" output 4.5dBm ?

Hi TTD,

Correct, the single-ended output power was measured using the EVM with the configuration as shown in Figure 169.
Both output buffers are identical, they can provide the same output drive.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
