I work for a company that builds (redacted for privacy), and a big company lent us a special GPS anti-jamming device, and I am in charge of implementing and testing it.
I already implemented the anti-jamming device and I am in the process of building a test GPS jamming device, there are plenty of buying options on the internet but I am going to build my own, as this interference research is also the topic of my masters thesis.
All the tests will be conducted at low transmission power at a remote location, provided by my company, to avoid any interferences. The amplifier used in the project has a low-gain mode and we also have plenty of attenuators available in case needed.
As this is my first RF design ever, this step will be just to try to transmit a square wave with duty cycle of 50% at a frequency of 1575Mhz. (i believe that that can accomplish jamming).
I want help validating the idea and the schematics seen below, I use a MCP1703 as a voltage regulator for both 5V and 2.8V, a CVCO55CC for generating 1575Mhz and a MC13851 amplifier, their datasheets are found below, I also based my designs on each of their evaluation boards. Also a DC source will be used in the place of the battery sometimes.
I also need to know if there are any tips in RF for then trying to draw the PCB layout.
