Designed for 3G and 4G wireless infrastructure applications
Richardson RFPD, Inc. recently announced immediate availability and full design support capabilities for a new high frequency, high power, 7-bit digital step attenuator (DSA) from Peregrine Semiconductor Corporation (Peregrine).
The PE43705 is the latest addition to this family of DSAs from Peregrine. An integrated digital control interface supports both serial and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. Covering a 31.75 dB attenuation range in 0.25 dB, 0.50 dB, or 1 dB steps, it maintains a monotonic step response from 50 MHz through 8 GHz. The PE43705 also features safe attenuation state transitions and is offered in a 32-lead 5x5 mm QFN package. In addition, no external blocking capacitors are required if 0V DC is present on the RF ports.
The new DSA is designed for use in 3G and 4G wireless infrastructure and other high performance RF applications.
Additional key features of the PE43705 include:
The PE43705 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS. Peregrine’s HaRP technology enhancements provide for new RF architectures and unmatched linearity in RF front end solutions.
