In every wireless system, the weakest link determines the performance of the network. In this paper the Radio Frequency (RF) performance of both band III and L-band Terrestrial Digital Audio Broadcasting (T-DAB) consumer receivers are discussed. The receivers have been tested based on the EN 50248 standard. The test results show that the average consumer receiver for band III meets the requirements set by EN 50248, except for the non-adjacent interferer experiments. In this experiment, the average consumer receiver performs up to 10 dB worse than required. In addition, the experiments reveal that there is a large difference in performance between consumer receivers. Besides band III, also L-band consumer receivers have been evaluated. The results of the L-band experiments show that the consumer receivers are not capable of decoding a DAB signal with a COST207 rural area channel model in case of T-DAB mode IV. Network operators should for this reason use mode II for the L-band and should expect a larger influence of non-adjacent interference on receiver performance in band III than anticipated based on EN 50248.Index Terms-Adjacent channel interference, band III, consumer receiver, EN 50248, in-band interference, L-band, nonadjacent channel interference, sensitivity, T-DAB.

“…DAB receivers have been developed for many years, however, most of the previous designs have less integration, large power consumption and high cost (as not CMOS technology based) [2]- [5]. The critical system design issues of DAB receiver RF front reported in [6] can provide useful practical guidelines to design low cost, compact, low power, highly integrated, and high performance DAB receiver RF front-ends for different applications.…”

A Band 3 receiver RF front-end for digital audio broadcasting (DAB) is described in this paper. The front-end integrates most of the functions necessary to receive and down convert Band 3 (174~245MHz) signals for further baseband processing, including a variable gain LNA, mixers, VGA, IF amplifiers, and PLL. The overall receiver gain is ≥90dB and NF is 4dB. Gain can be controlled over a range of over 95dB and IM3 remains above 60dB up to input levels of -10dBm. The linearity and dynamic range of this system is improved by using an external attenuator that has 30dB variable attenuation. Two AGC circuits (one for the RF part and another one for the IF part) are implemented in this receiver. An on-chip PLL based on integer-N architecture with P and S dividers is designed with integrated VCO generate all the LO frequencies. The prescaler used in the PLL realizes a divideby-64/65 stage. The front-end is designed in a standard 0.18µm CMOS process. The power consumption from a 3.3V power supply is 75mA.
