A 37 dBm power amplifier (PA) is designed on a 0.25 µm optical T-gate pseudomorphic high electron mobility transistor (pHEMT) technology. The design of this two-stage PA along with a step-by-step design procedure is presented in this paper. This methodology can be used for design of PA in different technologies and frequencies. The PA delivers 5 W output power over the frequency band of 13-19 GHz. It shows average power-added efficiency of 37% and large signal gain of 15 dB in measurements which is consistent with simulation results. The output power and efficiency of the realised amplifier reach maximums of 37.6 dBm and 45%, respectively. Considering output power, bandwidth, chip area and efficiency, this PA exhibits competitive performance compared to the reported PAs.

“…In a conventional radial power splitter, all the building quarter‐wave transmission lines have the first ends connected to the central input port and the second ends connected to the output ports locating radially around all directions. Each isolation resistor is placed between two adjacent output ports [1]. According to the theoretical analysis in [1], the conventional radial power splitter inherently cannot achieve decent output matching and isolation.…”

A radial power splitter is used to distribute signal power to the following stages locating radially around all directions. A well-known disadvantage of a radial power splitter implemented on a planar circuit board is the poor performance in output matching and output port isolation. An eight-way radial power splitter including the proposed ring-shape isolation network is presented. The ring-shape isolation network, comprising several series high-impedance lines and capacitors, plays the crucial role of significantly improving output matching and isolation of the eight-way power splitter. The background principle and design of the ring-shape isolation network are described. An eight-way radial power splitter is designed, simulated and fabricated on a printed circuit board. The measurement results, decently matching the simulations, show the input and output reflection coefficients as low as-20 dB at 1 GHz. The measured output isolation coefficients are below-20 dB at 0.7-1.14 GHz between any two output ports, exhibiting the widest isolation bandwidth among the reported radial power splitters.

A method is presented for broadbanding an n‐way power divider in which an absorbing resistor is used in one section. In the conventional Wilkinson power divider, it is known that the waves, equally reflected at the terminations, are absorbed by a resistor at the center frequency if a quarter‐wave line is connected to one of the output ports. To construct a 2n‐way power divider from a combination of these two‐way power dividers, 2n sections of lines are needed. In this paper, we constructed a network, which absorbs reflected waves, by connecting a 1/4‐wavelength section to an n‐way one‐section power divider if the characteristic impedance of the line and the absorbing resistor are optimized by numerical calculation. The circuit shown in the text has a broadband VSWR characteristic if attenuation of the transfer at the center frequency is permitted. The transmission characteristics then become flat, and the isolation characteristics are also improved.
