• ### A Low-Current Digitally Predistorted Direct-Conversion Transmitter With 25% Duty-Cycle Passive Mixer

Publication Year: 2014, Page(s):726 - 731

| | PDF (1591 KB) | HTML

A low-current direct-conversion transmitter (TX) is obtained by combining an efficient single-balanced 25% duty-cycle passive mixer with a low-bias single-ended driver. The nonlinearity of such architecture is aggravated by strong harmonics at the mixer output folding down to the fundamental frequency due to driver nonlinearity. To address this, a baseband mathematical model of the passive mixer p... View full abstract»

This paper presents a wideband 2 ×13-bit in-phase/quadrature-phase (I/Q) RF digital-to-analog converter-based all-digital modulator realized in 65-nm CMOS. The isolation between I and Q paths is guaranteed employing 25% duty-cycle differential quadrature clocks. With a 1.3-V supply and an on-chip power combiner, the digital I/Q transmitter provides more than 21-dBm RF output power within a ... View full abstract»

To demonstrate high tuning range and large output power, we propose a loop of coupled oscillators in this work. Two different tuning mechanisms are simultaneously exploited. First, each core oscillator is tuned using a variable capacitor. Next, by controlling the phase/delay between the coupled oscillators, the entire loop dynamics, and hence, its frequency is tuned. In this paper, we analyze a lo... View full abstract»

A novel technique for wideband injection locking in an LC oscillator is proposed. Phased-lock-loop and injection-locking elements are combined symbiotically to achieve wide locking range while retaining the simplicity of the latter. This method does not require a phase frequency detector or a loop filter to achieve phase lock. A mathematical analysis of the system is presented and the expression f... View full abstract»

| | PDF (1073 KB) | HTML

The slotted waveguide antenna stiffened structure (SWASS) utilizes conventional hat-stiffeners or blade stiffeners in aircraft sandwich structures as microwave waveguides. Slotted waveguide antenna arrays may therefore be integrated into the structure by machining slots through the outer skin. However, the primary mechanical load applied to the structure governs the orientation of these slotted wa... View full abstract»

In a seminal paper, Humblet decomposed the angular momentum of a classical electromagnetic field as a sum of three terms: the orbital angular momentum (OAM), the spin, and the more unfamiliar surface angular momentum. In this paper, we present the result of such decomposition for various metallic waveguides. We investigate two hollow metal waveguides with circular and rectangular cross sections, r...

Frequency independent fast-wave (FW) propagation with phase velocity greater than the speed of light can be ideally realized in a dielectric medium whose relative permittivity is positive, but less than 1. Conventionally, FW propagation is implemented by non-TEM waveguides or antiresonance-based metamaterials, which suffers from the narrow bandwidth due to the dispersion. In contrast, non-Foster c...

This paper proposes three novel models for behavioral modeling and digital pre-distortion (DPD) of nonlinear 2 × 2 multiple-input multiple-output (MIMO) transmitters in the presence of crosstalk. The proposed models are extensions of the single-input single-output generalized memory polynomial model. Three types of crosstalk effects were studied and characterized as linear, nonlinear, and n... View full abstract»

A novel balanced filter realized in the form of substrate integrated waveguide (SIW) is proposed and studied in this paper. Based on the inherently horizontal and vertical symmetry of the SIW, this filter presents inherently high-performance balanced property with advantages of no identical pair requirement, being free from the limitation of symmetrical topology, easy and flexible design, high com...

Over the last years, a great number of substrate integrated circuits has been developed. These new circuits are a compromise between the advantages of classical waveguide technologies, such as high quality factor and low losses, and the advantages of planar circuits, such as low cost and easy compact integration. Although their quality factor and losses are better than for planar circuits, these c... View full abstract»

| | PDF (2192 KB) | HTML

The turnstile junction exhibits very low cross-polarization leakage and is suitable for low-noise millimeter-wave receivers. For use in a cryogenic receiver, it is best if the orthomode transducer (OMT) is implemented in waveguide, contains no additional assembly features, and may be directly machined. However, machined OMTs are prone to sharp signal drop-outs that are costly to overall performanc... View full abstract»

A planar microstrip crossover is proposed by using a stub-loaded ring structure with lumped inductors to realize good transmission and isolation performances for three intersecting channels. It can take the place of three conventional dual-channel crossovers. Since the component is with a sixfold rotational symmetric configuration, it can be analyzed by using its eigen-admittances and the even-/od... View full abstract»

We present a near-field waveguide probe with an embedded array of split-ring resonators (SRRs) that operate at 16.65 GHz. When the probe scans a metal surface, the magnetic flux generated from the currents on the metallic surface strongly affects the equivalent lumped parameters of the SRRs. This, in turn, affects the reflection coefficient of the feeding port leading to high sensitivity in detect... View full abstract»

Flicker noise and dc offset have strong impacts on the performance of zero-IF receivers. In this paper, we propose a generalized approach to eliminate such impacts on zero-IF architecture pulse compression radars (PCRs). The conventional low-pass filter in a zero-IF receiver is replaced with a predefined filter (PDF) to filter out the dc and low-frequency components from the demodulated radar sign...

## Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
