> PWB means "Printed Wiring Board" (wire wrapped). I think you are going to have some serious problems doing a 1GHz system on a PWB. The amount of spurs and misc noise generated on the PWB will destroy the spectral purity of your system. You need impedance matching circuits and filtering, a PWB will make this extremely difficult. > > Best regards, > Steve "PWB" is just a synonym for "PCB", see http://www.pwbrc.org/faq10.cfm Bob Ammerman RAm Systems -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
