New from Peregrine Semiconductor come two UltraCMOS MPAC–Doherty products, the PE46130 and PE46140. These monolithic phase and amplitude controllers (MPAC) join the PE46120 in offering maximum phase-tuning flexibility for Doherty power amplifier (PA) optimisation. Designed for the LTE and LTE-A wireless infrastructure transceiver market, this product family now extends from 1,8 to 3,8 GHz with three separate, pin-compatible parts.
Because the devices are based on UltraCMOS technology, Peregrine claims they deliver intelligent integration benefits – reliability, flexibility, smaller footprint, configurability and greater system capability – that cannot be matched by gallium arsenide (GaAs) solutions. Each product eliminates the need for discrete components and 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.
The PE46130 and PE46140 are ideal for optimising gallium nitride (GaN)-based Doherty PAs, which are preferred at higher frequencies. Low-frequency Doherty amplifiers are typically based on laterally diffused metal oxide semiconductor (LDMOS) technology as LDMOS offers efficiency and cost advantages at frequencies less than 2,0 GHz. However, at higher frequencies, this efficiency breaks down and GaN-based Doherty PAs are used for their ability to maintain performance and meet high power density requirements. The UltraCMOS PE46130 covers a frequency range of 2,3 to 2,7 GHz and PE46140 extends from 3,4 to 3,8 GHz.
Aside from supporting different cellular frequency bands, the two chips are similar in their features and performance advantages. The controllers cover a phase range of 87,2 degrees in 2,8 degree steps and an attenuation range of 7,5 dB in 0,5 dB steps. They deliver high linearity of greater than 60 dBm IIP3 and low power consumption of 0,35 mA, while providing high power handling of 35 dBm P0.1dB and high port-to-port isolation of 30 dB.
