Is there a KiCad symbol and footprint for the HMC658LP2E?
Yes. The symbol is EasyEDA_Cloud:HMC658LP2E and the footprint EasyEDA_Cloud:TDFN-6_L2.0-W2.0-P0.65-TL-EP1.4, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HMC658LP2E?
TDFN-6-EP(2x2), with 7 pins. Its footprint is drawn on this page.
Where is the HMC658LP2E datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the HMC658LP2E?
JLCPCB lists it as part C1526004, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HMC658LP2E?
Parts like it in the library: the HMC653LP2E by Analog Devices, the YAT-3A+ by Mini-Circuits, the KAT-20+ by Mini-Circuits and the PE4312C-Z by pSemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
