L39, C449, C452 and C571 are placeholders. The actual values may change.
To start, L39 is 390nH. This is a coilcraft 0805CS-391XJBC.
- 390nH @100MHz
- Qmin = 48 @ 250 MHz
- SRFmin = 560Mhz
- Rdc Max = 1.5 Ohms
- Idc Max = 290mA
Doing the calculations the C452 capacitor want to be ~36 pf. The cicruit uses a 33pf to take into account some
board level capacitance.
To get a C_load of ~16pf, the assumption was made that the C_Stray will be about ~4pf. In this case C449 will
then want to be ~21pf. The design currently has a 20pf due to part availablitly.
As stated above, these values will be tewaked when the module is debugged in the lab.
