This letter presents the implementation of RF MEMS-based phase shifter with high power handling capabilities (measured IP3 >63 dBm), high phase, and amplitude linearity (measured rms deviation <+/- 1.56 degrees and +/- 0.16 dB) for cellular applications. Two phase shifter circuits are designed and tested with steps of +/- 3 degrees and +/- 17.5 degrees at 900 MHz to efficiently perform an electronic beam tilt for an eight-element array with more than 0.9 degrees accuracy and up to 10 degrees tilt can be obtained. The measured insertion and return loss for the largest phase state are 1.3 and 13 dB, respectively. For experimental validation, a 3 x 2 array of angled dipole patch antennas is designed and fabricated and four different scans are successfully measured showing a maximum deviation of +/- 0.6 degrees only for the scan angle.
