The output power of in the LMX2594 datasheet is a statement of the output power assuming no losses due to board, cable, or connectors. The LMX2594 EVM has board losses that cannot be ignored.

We don't have TINA /SPICE/or VHDH.
We have a IBIS model for the LMX2594, which is similar to the LMX2595.
Also, we have several other useful tools;
PLLatinum Sim can design your filter and simulate…

The statement of +7 dBm is for a theoretical lossless board with perfect matching with an inductor pull-up.
The standard EVM falls short of this for several reasons:
1. It has a resistor pull…
Toshiro-san,
The inductor should be high impedance at the frequency of interest. Theoretically, higher inductor values are better, but then you also have to stay away from the self-resonant frequency of the inductor.
1 nH might be good for the 9…

1. We do not have a lot of characterization data on this. If you have an output running, but the outputs are not terminated, we typically see much higher output harmonics. Now in terms of how much…

1) If decreasing the loop bandwidth degrades close in phase noise, it implies the VCO noise is cropping in the loop bandwidth, but I would expect that 150 kHz sould filter out VCO noise at 1 kHz…
