“…As a first-order of approximation, P max can be found through a straightforward analysis of the circuit shown in Fig. 1 based on transmission matrices [see (12)] when assuming that Z a , Z b and Z c satisfy the resonant conditions minimizing P th and when neglecting (for simplicity) any quadratic or cubic nonlinearities of the diode.…”

“…As an example, Fig. 3 shows a contour-plot capturing the analytically derived P max vs. Z tx and V DC [see (12)], assuming the same δ, f in and Z 0 values used during the derivation of Fig. 2, a V bi arbitrary set to 0.7 V (i.e., the built-in voltage for silicon diodes) and a C v value of 2.0 pF [i.e., the same used in our experimental demonstration when considering the additional parasitic capacitance (∼0.4 pF) associated to the diode's package].…”

As evident from both (12) and Fig. 3, P max values lower than 0 dBm and fairly insensitive to Z tx are obtained with low capacitance diodes requiring the use of low V DC values to operate.…”

“…Two main classes of FSLs have been previously discussed. One class relies on ferrite-based components [2]- [12], exploiting different types of nonlinear mechanisms in thin-film magnetic materials. While ferritebased FSLs employing different technologies have been explored, the intrinsic losses associated with any usable thin-film magnetic materials render these FSLs prone to high insertionloss values for small signals (IL s.s up to 10 dB).…”

This article describes the design methodology to achieve reflective diode-based parametric frequency selective limiters (pF SLs) with low power thresholds (P th ) and sub-dB insertion-loss values (IL s.s ) for driving power levels (Pin) lower than P th . In addition, we present the measured performance of a reflective pF SL designed through the discussed methodology and assembled on a FR-4 printed circuit board (PCB). Thanks to its optimally engineered dynamics, the built pF SL can operate around ∼2.1 GHz while exhibiting record-low P th (-3.4 dBm) and IL s.s (0.94 dB) values. Furthermore, while the pF SL can selectively attenuate undesired signals with power ranging from -3.4 dBm to 13 dBm, it provides a strong suppression level (IS > 12.0 dB) even when driven by much higher Pin values approaching 28 dBm. Such measured performance metrics demonstrate how the unique nonlinear dynamics of parametric-based FSLs can be leveraged through components and systems compatible with conventional chip-scale manufacturing processes in order to increase the resilience to electromagnetic interference (EMI), even of wireless radios designed for a low-power consumption and consequently characterized by a narrow dynamic range.

“…The applications of such FSLs to maintain the dynamic range of RF receivers require a strong DC-magnetic field in a monolithic microwave circuit (MMIC) configuration. Previous works, such as [21], address limiting the output power with a threshold level of -20 dBm with the primary goal of resolving interference issues in low power systems. In [22], it was outlined the characteristic of ferromagnetic-based limiters in the presence of multiple signals.…”

Reconfigurable Three Functional Dimension Single and Dual-Band SDR Front-Ends Using Thin Film BST-Based Varactors

This paper presents a performance evaluation of single and dual-band software-defined radio (SDR) front-ends using commercially available barium strontium titanate (BST) thin film to control SDR receivers dynamic range and mitigate interference. Firstly, an SDR front-end solution using a BST-based single-band bandpass filter (BPF) is developed to manage in-band attenuation according to the input power. Secondly, a dual-band SDR front-end to avoid high power interference with its spectral content on the below side of the second band is designed. This device is performed with a BST-based dual-band BPF providing independent control of the power limiting capabilities of the first and second bands. The BST component introduces a dependence on bias voltage, frequency, and input power. Consequently, by applying a 0 V bias, it is possible to target interferers between 700 MHz up to 1 GHz and attenuate them more than 7 dB at 40 dBm. The frequency dependence is defined by the second band, which retains its filtering performance while performing interference cancellation in the first band. This SDR solution implements a three functional dimension device in the upper MHz with a power-dependent insertion loss, high threshold power level, and frequency selectivity.INDEX TERMS dual-band bandpass filters, ferroelectric devices, frequency selectivity, intermodulation distortion, nonlinear measurements, power limiters, SDR front-ends, three functional dimension devices, tunable microwave filters.
