Digital Step Attenuator: PE4312

March 25, 2014

PE4312RFMW Ltd. announces design and sales support for the PE4312, 6-bit digital step attenuator from Peregrine Semiconductor. The PE4312 is designed for use in wireless infrastructure, portable radios and broadband infrastructure applications from 1 MHz to 4 GHz.

Key features include excellent attenuation accuracy +/- (0.15 + 2% of attn at 2.2 GHz) and low insertion loss. Parallel, serial and power-up controls settings allow the Peregrine PE4312 improved flexibility when programming within AGC loops. 1.8 V control logic is supported and supply voltage can range from 2.3 to 5.5V. Extended temperature range supports systems with passive / convection cooling.
