High Gain Broadband Power Amplifier Design Based on Integrated Diplexing Networks

IEEE Microwave and Wireless Components Letters, 2022
This letter presents an enhanced gain broadband power amplifier (PA) design approach that is based on using an integrated diplexer with a phase compensation network to combine PAs of narrower bandwidths (BWs) over a wider overall bandwidth PA.

A Broadband Power Amplifier in 130-nm SiGe BiCMOS Technology

IEEE Solid-State Circuits Letters, 2021
This letter describes an ultrabroadband power amplifier (PA) in a 130-nm SiGe:C BiCMOS technology. To achieve this broadband while keeping a compact chip size, an on-chip transformer-based dual- $LC$ -tank power matching method is proposed and ...

Broadband Diplexed Power Amplifier

IEEE Microwave and Wireless Components Letters, 2020
We present a diplexed power amplifier (PA) architecture for achieving more than octave bandwidth with high efficiency. Two relatively narrowband single-stage PAs are connected with a contiguous diplexer-combiner network. The average efficiency across the larger than octave band is maintained with a flat gain response from 1.8 to 4 GHz.

Broadband Power Amplifier Based on a Generalized Step-Impedance Quasi-Chebyshev Lowpass Matching Approach

IEEE Transactions on Plasma Science, 2020
In this article, a 1.7–2.6-GHz broadband power amplifier (PA) was proposed using the generalized quasi-Chebyshev lowpass matching approach, which was directly composed of step-impedance transmission lines (SITLs).

Broadband power amplifier using hairpin bandpass filter matching network

Electronics Letters, 2020
This Letter presents a new combination of a broadband power amplifier (PA) and an output microstrip hairpin bandpass filter. The filter is designed based on the fifth-order Chebyshev low-pass prototype element values.

Broadband Techniques in Power Amplifiers

2020
This chapter describes the design challenge and methodology to achieve the best bandwidth out of continuous mode PAs with feasible matching networks. The bandwidth expansion scheme for load modulation-based PA such as Doherty PA and Chireix outphasing PA are also described in this chapter. In addition, for multi-octave PA design, the reactively matched

Broadband Doherty power amplifiers

2013 IEEE Topical Conference on Power Amplifiers for Wireless and Radio Applications, 2013
In this paper, the transformer-less load-modulated (TLLM) architecture for designing broadband Doherty amplifiers is presented. In this architecture, the quarter-wave impedance transformers of the Doherty amplifier are not used. As a result, the design will be much more compact and large operational bandwidths can be obtained.
