We would like to hire someone to design (no PCB needed, only schematic but the simulation needs to be as accurate as possible) a crystal notch at a specific frequency (in the MHz). We already have the quartz, we also have every parameters of each piece (Fs, Fp, Cs, Cp, Q, Rs ...) This filter needs to be matched at 50ohm IN and OUT. Attenuation

I need a simple 8 circuit common bus pcb designed. Each of the 8 common busses should have 18 holes that can accommodate 18AWG stranded wire. I'd also like there to be a test point for each of the 8 busses. The test points will need to be multimeter probe friendly so that a technician can plug one of the multimeter's probes in one test point and
Hi, I have 3 PCB files that need modification in PADS. Changes have already been made in Altium for same PCB files, but i want same changes to be done in PADS.
I need someone to either design a motherboard for me from scratch or work with the one that i have started designing in eagle. I would prefer the design to be made in eagle but other cad software's are OK too. the dimensions of the board should be in approximately a 2:1 ratio and can be any size smaller than 154/77mm. The board should be as thin
