چکیده

This paper presents a broadband GaN pseudo high-electron-mobility transistor (pHEMT) two-stage driver amplifier based on an enhanced feedback technique for wideband system. Through well-designed parameter values of the and matching structure circuit, relatively flat frequency response was obtained over wide band. Simultaneously, in order to reduce fluctuation current caused by environmental temperature, bias circuit with quiescent temperature compensation designed. The power amplifier, which implemented form monolithic microwave integrated (MMIC), designed drive high-power amplifier. 6 GHz 20 band had very small die size 1.5 × 1.2 mm2 due use optimized impedance structure. It exhibited small-signal gain 12.5 dB output 26 dBm. flatness this achieved as ±2.5 ±1 entire band, respectively. experimental results showed up 35 dBm OIP3, variation range ±5 mA after using circuit.

Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmitters

The design of predistortion techniques for broadband multiple input multiple output-OFDM (MIMO-OFDM) systems raises several implementation challenges. First, the large bandwidth of the OFDM signal requires the introduction of memory effects in the PD model. In addition, it is usual to consider an imbalanced in-phase and quadrature (IQ) modulator to translate the predistorted baseband signal to ...

Fast-Settling Amplifier Design Using Feedforward Compensation Technique

A new feedforward compensation amplifier architecture that provides very fast settling performance is introduced. The additional feedforward path introduces zeros in the open-loop transfer function which can be used to shape the overall frequency response. It is shown that a second-order bandpass feedforward path is useful for extending the unitygain-frequency of the overall amplifier. By choos...

Design of Broadband, Highly and 35-45 GHz MMIC

The design of broadband, highly integrated up-converters is described. Two up-converters have been designed to reduce the complexity and cost of broadband millimetre wave systems by integrating a number of functions into a compact MMIC. Broadband performance was achieved for 20-30 GHz and 35-45 GHz with OIP3 exceeding 24 and 15 dBm, respectively; 2xLO leakage better than 3 dBm and excellent gai...
