Peregrine Semiconductor introduces a new family of Digital Step Attenuators (DSAs). The family of devices, including the 6-bit PE4302 and PE4304 components, is manufactured using UTSi( RF CMOS Silicon-on-Sapphire technology. The PE4302 and PE4304 devices are 50 and 75Ω, 6-bit DSAs with a 0.5 dB LSB, positive logic serial and parallel interface, single +3.0 volt supply, and a unique power-up preset feature. Guaranteed Return Loss (RL) for the PE4302 is 15 dB through 2.2 GHz. The PE430X DSA devices also include a preset power-up attenuation state.
