LMX2592: Wideband VCO which can create a frequency ramp from 100MHz to 350MHz

Part Number: LMX2592
Other Parts Discussed in Thread: LMX2572

Hi Team,

I would like to ask if we have an RF PLLs & synthesizer product which can create a frequency ramp from 100MHz to 350MHz or is this request of our customer possible to attain our available TI products?

The customer first asks if LMX2592 can do this but I found that this device do not have a frequency ramp/chip feature.

Another specification of the customer is a low phase noise and output close to 0 dBm.

Let me know if you need more information.

Thanks!

Jonathan.

    Hi Jonathan,

    Unfortunately we don't have a PLL/synthesizer that can support 100MHz to 350MHz automatic ramp. This is because a fixed output divider value cannot support this freq ramp range.

    You can try LMX2572 in manual ramp mode. With this mode, you have the flexibility to change the output divider value whenever necessary.
