Abstract

Future software-defined radios (SDRs) for modern wireless applications—e.g., 5G communications—could require reconfigurable RF analog circuits to enable multistandard/service operation with hardware miniaturization. In this context, a lumped-element multi-band bandpass filter concept is presented. This filter architecture consists of the in-series cascade of several multi-transmission-zero-(TZ)-generation cells that are shaped by a plurality of series-type resonant branches. It allows to synthesize multi-band transfer functions with arbitrary order and number of passbands with inter-band TZs. A theoretical analysis of the proposed multi-passband filter scheme is expounded. Also, its potential for fully-reconfigurable multi-band bandpass filter realization through TZ reallocation is studied at the ideal-design level.

Abstract

In this paper, an integrated RF differential channelized active bandpass filter is presented. The proposed filter architecture is implemented with two tunable bandpass N-path filters that are arranged in parallel to create one upper-stopband transmission zero that allows to increase the selectivity in the overall filtering transfer function. The channelized bandpass filter can be frequency tuned from 0.2 GHz to 1 GHz (i.e., 5-to-1 tuning range). The gain, noise figure (NF), and channel bandwidth of the filter are around 21 dB, 4.7 dB, and 6 MHz, respectively. The circuit has been designed with 0.25 μm BiCMOS process of NXP technology using Cadence SpectreRF circuit simulator.
