5 device boards. These loads have low control bandwidth and will cause will severely damage the VNA. the EPC9129 system to oscillate at a low frequency and may lead to failure. It is recommended to use a fixed low inductance resistor as an initial load. Once a design matures, a post regulator, such as a Buck converter, can be used. - Page 7 Figure 5: Schematic diagram of the EPC9513 and EPC9514 demo board. f = 6.78 MHz ON-OFF KEY modulation Figure 6: ON-OFF-KEY modulation.
