摘要
设计了用于有源集成相控阵天线(AIPAA)波束方向控制的5.8 GHz频段数字移相器。集成GaAs FET SPDT开关的4位移相器集成在LTCC衬底上。我们实现了一个低损耗的4位LTCC移相器，尺寸为10 mm × 13 mm × 0.55 mm。从仿真结果来看，不带开关的LTCC移相器的插入损耗仿真值约为0.5dB/bit。与GaAs FET SPDT开关集成的LTCC移相器的插入损耗和相位误差分别为2.3dB/bit和小于15°。此外，利用16元有源集成相控阵天线的10 Mbps MSK信号，成功实现了±30度角的波束扫描。
A 16-element power AIPAA with a 4-bit digital LTCC phase shifter operating at the 5.8 GHz-band for wireless communication and power transmission
5.8 GHz band digital phase shifters to control a beam direction for an Active Integrated Phased Array Antenna (AIPAA) are designed. The 4-bit phase shifters with integrated GaAs FET SPDT switches are integrated with an LTCC substrate. We realized a low loss 4-bit LTCC phase shifter with the size of 10 mm × 13 mm × 0.55 mm. From the simulation results, the insertion loss of LTCC phase shifter without the switch is simulated with about 0.5dB/bit. The insertion loss of the LTCC phase shifter integrated with the GaAs FET SPDT switches and phase error are measured to be about 2.3dB/bit and less than 15°, respectively. In addition, beam scanning with angles of ±30 degrees was successfully achieved with 10 Mbps MSK signal from the 16-element active integrated phased array antenna.
