Andrey Sviyazov andrey.sviyazov at fairwaves.ruHi Thomas. Digikey part numbers links: C82 = 100pF<http://www.digikey.com/product-detail/en/C0603C101J5GACTU/399-1061-1-ND/411336>, C83=1500pF<http://www.digikey.com/product-detail/en/C0603C152K5RACTU/399-1084-1-ND/411359>, C84=33pF<http://www.digikey.com/product-detail/en/C0603C330J5GACTU/399-1055-1-ND/411330>, R106=2.2k<http://www.digikey.com/product-detail/en/RMCF0603JT2K20/RMCF0603JT2K20DKR-ND/1944084>, R109=3.3k<http://www.digikey.com/product-detail/en/RMCF0603JT3K30/RMCF0603JT3K30CT-ND/1943182>, L6=0.022uF<http://www.digikey.com/product-detail/en/C0603C223K5RACTU/399-1280-1-ND/416056> . But you'll remove 100pF capasitor from position C45, so you could use it for C82. BTW, how long time required to delivering from the DigiKey? Best regards, Andrey Sviyazov. 2012/7/25 Thomas Tsou <ttsou at vt.edu> > Hi Andrey, > > I will need to order parts.
