Digitally Tunable Capacitors

Embedded Technology INSIDER

Peregrine Semiconductor Corporation (San Diego, CA), a fabless provider of high-performance radio frequency integrated circuits (RFICs), announced that it has expanded its DuNE™ Digitally Tunable Capacitor (DTC) product line with six second-generation devices for antenna tuning in 4G LTE smartphones. The PE623060, PE623070, PE623080, and PE623090 (PE6230x0) DTCs have a capacitance range of 0.6 – 7.7 pF and support main antenna power handling of up to +34 dBm. The PE621010 and PE621020 (PE6210x0) DTCs have a capacitance range of 1.38 to 14.0 pF and are optimized for power handling of up to +26 dBm, making them well suited for diversity antennas. All of the new DTCs are manufactured on Peregrine’s UltraCMOS® technology process, with HaRP™ technology enhancements that enable the devices to meet the challenging harmonic and linearity requirements of LTE. The highly-versatile devices support a wide variety of tuning circuit topologies, with an emphasis on impedance matching and aperture-tuning applications.
