PE43705 - RF Digital Step Attenuator

General Description

The PE43705 is a 50Ω, HaRP™ technology-enhanced, 7-bit RF Digital Step Attenuator (DSA) designed for use in 3G/4G wireless infrastructure and other high performance RF applications.

Key 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 PE43705 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. Peregrine’s HaRP™ technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the per.

Product Description The PE43705 is a 50Ω, HaRP™ technology-enhanced, 7-bit RF Digital Step Attenuator (DSA) designed for use in 3G/4G wireless infrastructure and other high performance RF applications. This DSA is a pin-compatible upgraded version of PE43703 with higher power handling and a wider frequency, control voltage and operating temperature range. 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. PE43705 also features safe attenuation state transitions and is offered in a 32-lead 5x5 mm QFN package.
