Claiming new levels of broadband linearity, attenuation accuracy, and programming flexibility, the PE4302 and PE4304 digital step attenuators (DSAs) maintain an IP3 of greater than ±50 dBm across steps from 1 MHz to 2.5 GHz. Both are 50? and 75?, 6-bit DSAs with a 0.5 dB LSB and include positive-logic serial and parallel interfaces. They operate from a single 3V supply and feature what is reported as a unique power-up preset feature. Available in 20-lead QFN packages, both devices specify an insertion loss of 1.5 dB. In addition, the PE4302 specifies a guaranteed return loss of 15 dB through 2.2 GHz. For more details, call PEREGRINE SEMICONDUCTOR CORP., San Diego, CA. (858) 455-0660.
