Product Description
The PE43711 is a 50, HaRP™ technology-enhanced, 7-bit RF digital step attenuator (DSA) that supports a
broad frequency range from 9 kHz to 6 GHz. It features glitch-less attenuation state transitions and supports
1.8V control voltage and an extended operating temperature range to +105 °C, making this device ideal for
many broadband wireless applications.
The PE43711 is a pin-compatible upgraded version of the PE43502, PE43503, PE43602 and PE43702. 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.
The PE43711 covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB and 1 dB steps. It is capable of
maintaining 0.25 dB monotonicity through 4 GHz, 0.5 dB monotonicity through 5 GHz and 1 dB monotonicity
through 6 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports.
The PE43711 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate.

PE43711
UltraCMOS® RF Digital Step Attenuator
Peregrine’s HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an
innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and
integration of conventional CMOS.
Absolute Maximum Ratings
Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be
restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for
extended periods may reduce reliability.
ESD Precautions
When handling this UltraCMOS device, observe the same precautions as with any other ESD-sensitive devices.
Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to
avoid exceeding the rating specified in Table 1.
Latch-up Immunity
Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.
