Wireless interconnection within a hybrid engine controller board

Wireless interconnection within a hybrid engine controller board has been demonstrated by demodulating an AM signal transmitted with an on-chip antenna using a receiver located in the board. The receiver centered between 14 and 16 GHz uses a Schottky diode detector and should be able to support 400-Mbps data rate and ~15 cm range. The receiver does not require a crystal frequency reference. The measured peak conversion gain is ~35 dB, sensitivity over the band with minimum E b /N o of 14 dB for ASK is -58 dBm. The receiver occupies ~1.5 mm 2 and consumes ~60 mW.
