Datasheet Summary
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.
This DSA is a pin-patible upgraded version of the PE43204 with a wider frequency and power supply range, and extended operating temperature range.
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.
The PE43205 is manufactured on pSemi’s...
