Product Specification

PE43205

UltraCMOS^®RF Digital Attenuator

2-bit, 18 dB, 35–6000 MHz

Product Description

The PE43205 is a 50Ω, HaRP™ technology-enhanced

fast switching 2-bit RF Digital Step Attenuator (DSA)

designed for use in 3G/4G wireless infrastructure and

other high performance RF applications.

Features

 Attenuation: 6 dB / 12 dB steps to 18 dB

 Fast switching time of 29 ns

 Low attenuation error

 0.10 dB @ 2 GHz

 0.15 dB @ 3 GHz

This DSA is a pin-compatible upgraded version of the

PE43204 with a wider frequency and power supply range,

and extended operating temperature range.

 High linearity

 +61 dBm IIP3 @ 1950 MHz

 Wide supply range of 2.3V to 5.5V

 1.8V control logic compatible

 105°C operating temperature

Covering an 18 dB attenuation range in 6 dB and 12 dB

steps, it maintains high RF performance and low power

consumption from 35 MHz through 6 GHz. PE43205 is

offered in a 12-lead 3x3 mm QFN package. In addition,

no external blocking capacitors are required if 0 VDC is

present on the RF ports.

 ESD performance

 2 kV HBM on all pins

 100V MM on all pins

 1 kV CDM on all pins

The PE43205 is manufactured on pSemi’s UltraCMOS^®

process, a patented variation of silicon-on-insulator (SOI)

technology on a sapphire substrate.

 Parallel control

pSemi’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.
