The implemented ASICs, intended for mobile terminal usage, comprise a wideband high capacity OFDM direct conversion transceiver front-end for beyond 3G cellular systems. The transceiver operates with 83.2 MHz signal bandwidth and is designed for the operational frequency range of 5.15-5.725 GHz. The receiver and transmitter chips were fabricated with(More)
This paper presents a digital interpolation chain for non-integer variable-ratio sampling rate conversion, targeted to 4G mobile applications. Such a system is needed in all-digital transmitters, where the sampling rate of the digital input to the RF front-end must be an integer fraction of the carrier frequency. A highly configurable architecture is(More)
