AWR Publishes Millimeter-Wave Wireless System Application Note

AWR recently published a news application note: Design of a Full ETSI E-band Circuit for a Millimeter-Wave Wireless System. The article explains how to use Microwave Office circuit design software to develop a Q- to E-band doubler and a K- to E-band quadrupler circuit (including a medium E-band power amplifier) for millimeter-wave wireless systems. The design effort resulted in an increase in gain as well as output power, two critical criteria for E-band systems.
