yes 3dB, times 2. my head doesnt work well yet in dB... if few KHz to 7GHz range is considered wideband, then yes, preferably wideband. i may not know what i'm talking about. but i can see some smd inductors and resistors in the linked ebay module above, i need to know how is that done... another reason to build my own is for learning so in the future i may design my own circuit. thank david for the link i will try to digest the pdf. the linked ebay module pcb seems to simple that i think not necessating simulation, just a ground plane, and shortest possible tracks, or possibly impedance controlled, no? as i said i may not know what i'm talking about. david, yes i may need the mmic, but since the gain i want is 2X (3dB) so may need something like > 14GHz GBW MMIC, correct?
