Product Description
The PE43712 is a 50Ω, 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 PE43712 is a pin-compatible upgraded version of the PE43601 and PE43701. An integrated digital control
interface supports both Serial Addressable and Parallel programming of the attenuation, including the capability
to program an initial attenuation state at power-up.
The PE43712 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 4GHz, 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 PE43712 is manufactured on Peregrine’s UltraCMOS^® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate.
