Maximum Phase-Tuning Flexibility for LTE and LTE-A

pSemiā€™s family of MPAC products optimizes system performance while reducing manufacturing costs of transmitters that use symmetric or asymmetric Doherty power amplifier designs.

Each MPAC integrates a 90-degree RF splitter, 5-bit digital phase shifters, a 4-bit digital step attenuator and a digital serial peripheral (SPI) interface on a single monolithic die.

  • Phase range: 87.2° in 2.8° steps
  • Attenuation range: 7.5 dB in 0.5 dB steps
  • Excellent phase and amplitude accuracy
  • Exceptional linearity
  • High port-to-port isolation
  • Extremely low power consumption
