A 20～40 GHz Broadband High-Precision Six-Bit Digitally Controlled Phase Shifter
摘要
Abstract
In order to meet the high-precision design requirements of Ka-band wireless communication systems,a 20-40 GHz wideband high-precision six-bit digitally controlled phase shifter is designed in this study using the GaAs 0.15 μm PHEMT(Pseudomorphic High Electron Mobility Transistor)process.By cascading six different phase shifts,a phase shift range of 0° to 360° with a minimum step of 5.625° can be achieved.Among them,the 5.625° phase shift adopts a symmetrical CLC embedded switch linear structure,while the 11.25° and 22.50° phase shifts a-dopt a bridge T-type topology.The 45° and 90° phase shifts adopt the Lange coupler-type reflective structure,while the 180° phase shift adopts the switch-selective structure based on the Lange coupler.The electromagnetic simulation results show that within the frequency band range of 20～40 GHz,the 64-state phase RMS(Root Mean Square)error of the phase shifter is less than or equal to 5°,both the input and output return losses of the port are greater than 10 dB,the insertion loss is less than 10 dB,and the 64-state insertion loss fluctuation of the phase shifter is less than±0.6 dB.关键词
