    Hi All, I'm looking for some help designing a few small PCB layouts. My end goal is to have 4 independent wireless MEMS accelerometer boards that transmit data to a micro-controller board. The micro-controller also will have a bluetooth module so data can be output to a cell phone or laptop. The 3-axis accelerometers will be sampled somewhere in the frequency range of 1-2kHz (to accurately measure vibration). I should note that, as a mechanical engineer, I have minimal ...

    We are looking for a contractor to help us with simulations for a PCB antenna. HANDS ON EXPERIENCE WITH IE3D IS A MUST. The work includes the following steps: 1. Antenna simulation for free space (Base Design) -- simulate the return loss and radiation pattern and prove that the simulation is consistent with the reference design. DELIVERABLE 1: Charts, graphs, etc showing that the simulation for the Basic Design is consistent with the reference design from the manufacturer and provide the ...
