LMX2491: Power for Fin Pin

Hao Wang14

Part Number: LMX2491
Other Parts Discussed in Thread: LMX2492,

Hi Team,

The datasheet only has the min and max value of power for Fin pin, I have three questions:

1. What's the min power for Fin pin when the frequency is 1.6GHz?

2. Is there a power vs frequency graph for LMX2491 which is similar with the LMX2492?

3. What does the "Design to electrical specifications for input sensitivity, not typical performance graphs" mean in figure 3 of LMX2492?

Thanks and Best Regards!

Hao

    Hi Hao,

    The min. and max. Fin input power specified in the Electrical Characteristic is the required Fin input power range. Your design should meet this requirement for robust operation over temperature. In LMX2492 datasheet, Figure 3 was showing a "typical" performance measured with a few devices at room temperature. Again, your design should have Fin power between -5dBm and 5dBm.
