“…Following the trend of miniaturization of communication systems, the design of multifunctional components has become a hot research topic in recent years. As one of the most important passive circuits, power divider is widely used in radio frequency and microwave circuits . The power divider with bandpass filtering response or called filtering power divider is attractive for its simultaneous compact size, high efficiency, and multiple functions of power divider as well as the frequency selectivity.…”

A novel differential power divider with bandpass filtering response using the substrate integrated waveguide (SIW) technology is presented. An SIW resonant cavity operated in a balanced resonant mode with odd symmetric electric field distribution is utilized to provide both balanced inputs/outputs and expected common-mode (CM) suppression in a certain band. Meanwhile, by properly constructing the cross-coupled topology of SIW resonant cavities, the proposed differential power divider achieves a high-selectivity bandpass filtering response with two transmission zeros on both sides of the passband. The differential power divider is designed and prototyped on a single-layer printed circuit board (PCB). The measured center frequency is at 10.6 GHz with 490 MHz 3-dB bandwidth. A good CM suppression can also be achieved within the operating band. The measured in-band differential-mode imbalance for magnitude is 60.3 dB, while for phase is 08-48.

Purpose The purpose of this paper is to propose a new design strategy to enhance the bandwidth and efficiency of the power amplifier. Design/methodology/approach To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka-band, i.e. the frequency range of 26.5-40 GHz. To design the power amplifier, first, a power divider (PD) with a very wide bandwidth, i.e. 1-40 GHz, was designed to cover the whole Ka-band. The designed Doherty power amplifier consisted of two different amplification paths called main and auxiliary. To amplify the signal in each of the two pathways, a cascade distributed power amplifier was used. The main reason for combining the distributed structure and cascade structure was to increase the gain and linearity of the power amplifier. Findings Measurements results for designed power dividers are in good agreement with simulations results. The simulation results for the introduced structure of the power amplifier indicated that the gain of the proposed power amplifier at the frequency of 26-35 GHz was more than 30 dB. The diagram of return loss at the input and output of the power amplifier in the whole Ka-band was less than −8dB. The maximum power-added efficiency (PAE) of the designed power amplifier was 80%. The output P1dB of the introduced structure was 36 dB and the output power of the power amplifier was 36 dBm. Finally, the IP3 value of the power amplifier was about 17 dB. Originality/value The strategy presented in this paper is based on the usage of Doherty and distributed structures and a new wideband power divider to benefit from their advantages simultaneously.
