✦ Synopsis

A new SPDR design approach is proposed. The recei¨er contains an RF discriminator, power detectors, a signal le¨el comparison circuit, a decoder, and data and carrier reco¨ery circuits for BPSK and QPSK signals. The new recei¨er operates solely on analog circuits, and the proposed design is ¨alidated with circuit and system simulations of an RF discriminator and a Costas-type phase-locked loop, demonstration of a demodulator at 2.4 GHz, and MMIC fabrication of an RF discriminator at 15 GHz. The new design approach offers interesting possibilities to achie¨e SPDR-on-a-chip.
