In this installment of WiGaN, a differential-mode class-E amplifier for 6.78 MHz loosely coupled resonant wireless power applications is presented. It uses the EPC2037 eGaN® FET which has a small (0.9 mm x 0.9 mm) footprint and can be driven directly with a logic gate. The amplifier is AirFuel™ Class 2 compatible, capable of delivery up to 6.5 W load power over an impedance range of 70j Ω.
