“…In, 24 a reflection‐type attenuator is presented by using PIN diode terminated with the open‐circuited transmission line (TL), which provides low insertion phase variation only at the single center frequency. Similarly, reflection‐type and transmission‐type attenuators have been presented in 25 without any results of the flat amplitude error and insertion phase variations. In, 26 a variable attenuator is presented by using TL terminated with a PIN diode, which provides low insertion phase variation with high attenuation range only at around center frequency.…”

“…27 In, [28][29][30][31] substrate integrated waveguide attenuators were presented. Despite significant research in the field of analog/digital attenuators, the previously presented works [19][20][21][22][23][24][25][26][27][28][29][30][31] are mainly focused on amplitude control rather than simultaneous flat amplitude error and insertion phase variations minimization, which are significantly essential for phased array and beamforming systems in wireless communication systems.…”

This paper presents a design of an analog variable attenuator with simultaneous minimized flat amplitude error and insertion phase variation over a wide bandwidth and high attenuation range. The parasitic of PIN is compensated with series transmission lines loaded and shunt capacitors to achieve minimum flat amplitude error and insertion phase variation. Mechanism for simultaneous reduction in flat amplitude error and phase variations is obtained by developing an analytical design equation using the PIN diode equivalent circuit model. For the experimental validation, two kinds of proposed attenuators are designed and measured over 1 GHz bandwidth at a center frequency (f 0 ) of 3.5 GHz. The measurement results are consistent with the simulation results. From the experiments, design-I provides an attenuation variation of 0.9 dB to 20 dB with a maximum flat amplitude error of 0.65 dB and insertion phase variation of 5.70 over 1 GHz bandwidth. Similarly, the design-II provides an attenuation variation of 1.06 dB to 20 dB with a maximum amplitude error of 0.49 dB and insertion phase variation of 3.19 over the same 1 GHz bandwidth.

This paper proposes an innovative design approach for a voltage‐controlled (variable) attenuator that allows continuous control of attenuation through analog voltage. Different from fixed attenuators, this work employs PIN diodes and compensated gold wire inductors to configure the attenuation network. It is based in imperfect matching theory, ensuring to obtain the acceptable S‐parameters over the operating band. Measurement results demonstrate effective performance of the attenuator within the voltage range of 0.7–1.03 V. Return losses of the attenuator are all better than 15 dB in the operating range of 10.5–19 GHz. The insertion losses exhibit continuous variation from 2 to 15 dB, requiring only a single controlled voltage to adjust the attenuation value.
