“…The proposed PA was compared with other published broadband PAs, as shown in Table I. Although the proposed design did not provide an operating bandwidth as broad as those in [7], [9], and [15], it is worth noting that those three designs either forfeited second harmonic control or transferred PA modes, leading to a lower DE and a smaller saturated output power. Compared with [10], [13], and [14], the proposed PA exhibited a greater fractional bandwidth with a higher gain, a larger output power, and a higher DE simultaneously.…”

“…To date, many impedance matching techniques have been thoroughly explored. In particular, multistage, low-pass topologies are often utilized for this task [7]- [15]. For instance, a synthesized Chebyshev low-pass filtering (LPF) matching network (MN) based on series transmission-lines and open-circuit stubs were used in a highly efficient broadband Class-E PA [8].…”

A 1.8 GHz broadband high power amplifier (PA) with 144% fractional bandwidth is presented in this article. The proposed PA achieves a power added efficiency of 40%–56% for the entire band. To ensure flat gain response, a novel idea of integrating a microstrip high pass filter (HPF) in the input matching network is proposed. The incorporation of HPF reduces the unusual high gain at low frequency and thus results in a flat gain of 14.4 ±1 dB for the entire band. The matching circuits are realized on Taconic RF35 with dielectric constant of 3.5 and thickness of 0.76 mm. The high fractional bandwidth of the proposed PA makes it suitable to be used for the recent and future wireless communication systems.

“…The rapid development of wireless and optical communications makes the total bandwidth of the commercial mobile communication technology cover a wide bandwidth more than one octave, and the low cost is expected for the base-station transceivers, which drives the high efficiency and broadband power amplifier (PA) [1]. Distributed amplifiers (DAs) provide an effective approach for extending the bandwidth and therefore are widely used in the design of ultra-wideband systems.…”

A 1-20 GHz distributed power amplifier (DPA) with a novel compact structure is designed and implemented in a commercial 0.18 µm CMOS technology. The proposed DPA consists of two distributed amplifiers (DAs), which have separate input artificial transmission lines (ATLs) but with their output ATLs shared to achieve high output power and efficiency in the wide frequency band. The gradually changed output ATL is used to further improve the power performance. Measurement results show that the DPA achieves 9.6 dB average associated gain from 1 to 20 GHz. The output power at 1-dB output compression point (OP 1dB ) is more than 8.2 dBm, and the peak power-added efficiency (PAE) is 9.6% with the OP 1dB of 12.9 dBm at 4 GHz.
