Design of a Full ETSI E-band Circuit for a Millimeter-Wave Wireless System

This application note highlights how the design of a Q- to E-band doubler and a K- to E-band quadrupler circuit (that includes a medium E-band power amplifier) results in an increase in both gain and output power. The doubler provides 15dBm over the full ETSI E-bands. The quadrupler design provides more power over a narrower bandwidth such as might be used for a radio system with an LO between the two E-bands. This quadrupler produces a maximum of 19.2dBm. The power amplifier produces more than 200mW (23dBm) over the two ETSI E-bands and a maximum power of 24.2dBm (265mW).
