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. 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
performance of GaAs with the economy and integration of
conventional CMOS.
