Maximum Phase-Tuning Flexibility for LTE and LTE-A

pSemi’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
