Popis:	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.
