“…The receiver design is governed by the signal characteristics of the Eureka 147 DAB system [3] and its environment Relevant characteristics of this system are therefore discussed first, followed by details of the receiver and AGC circuit designs and performance evaluations. The signal path circuit design and performance of both the RF and IF chips are discussed in [4]and [5], respectively.…”

A novel, dual conversion architecture for the Digital Audio Broadcasting (DAB) dual band receiver is introduced. It avoids preselection filters and mini. mizes the number of PLLs by first converting both Lband and Band m inputs to a common 919 MHz intermediate frequency (IF) signal which is then downconverted to the 30 MHz ADC input A carefuily staged gain control strategy is used to meet the challenging sensitivity and intermodulation requirements.Introduction.

Bandpass filters are integral in modern communication systems for selecting specific frequency ranges to ensure interference-free signal transmission and reception. This paper explores various bandpass filter designs, including those using active inductors, transmission-line unit-cells, microstrip open-loop resonators, and dual-port dual-frequency integration antennas. The focus is on the 10.7-MHz bandpass filter, widely used in FM radio and television systems. The study evaluates current-controlled and balanced designs, analyzing their performance, advantages, and drawbacks. Unique trade-offs in terms of linearity, distortion, temperature sensitivity, and component variations are discussed. Additionally, advancements in filter technology and diverse design options are presented. The paper introduces a novel current-balanced, frequency-adjusted bandpass filter to address odd-order noise issues. This filter aims to achieve high linearity, harmonic distortion attenuation, and the elimination of even-order harmonics. Through synthesis, analysis, simulation, and comparison with traditional filters, the proposed design enhances signal quality and efficiency. The fully-balanced current-tunable bandpass filter with the Caprio technique at 10.7 MHz is developed, exhibiting symmetrical characteristics with lower total harmonic distortion. The circuit’s structure is simple and adaptable for integration, validated through consistent simulation results. The study concludes by emphasizing the constant sensitivity of transistor differential amplifier circuits to the center frequency and the linear relationship between center frequency and adjustable bias current. The suggested transistor and capacitor selection criteria contribute to optimizing the circuit’s performance, aligning with the Caprio technique’s recommendations. Overall, this research presents a promising solution for achieving high-quality signal transmission in contemporary communication systems
