12.5 GHz band digital phase shifters to control a beam direction for an Active Integrated Phased Array Antenna (AIPAA) are designed and fabricated an RF-MEMS device and a LTCC substrate. We designed and fabricated low loss RF-MEMS wave guide (Lt0.5 dB) and 4-bit LTCC phase shifters with small-size (10 mm times 13 mm times 0.55 mm). From the experiment data, the insertion loss of RF-MEMS device and...
5.8 GHz band digital phase shifters to control a beam direction for an active integrated phased array antenna 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 times 13 mm times 0.55 mm. From the simulation results, the insertion loss of LTCC phase shifter without...
