PE4312C-Z Description

Short technical summary and product information.

The PE4312C-Z from pSemi is a 6-bit RF Digital Step Attenuator (DSA) utilizing HaRP technology. It is designed for 3G/4G wireless infrastructure and other demanding RF applications. This DSA provides a wide attenuation range of 31.5 dB, adjustable in precise 0.5 dB steps, covering frequencies from 1 MHz up to 4 GHz.

Key electrical specifications include a 50 Ohm impedance, high linearity with a +59 dBm IIP3, and an input 0.1dB compression point of 30 dBm. The device operates over a wide power supply range of 2.3V to 5.5V and is compatible with 1.8V control logic. It features safe attenuation state transitions and unique power-up state selection.

The PE4312C-Z is manufactured on pSemi's UltraCMOS® process. It is supplied in a compact 20-lead, 4x4 mm QFN package, suitable for space-constrained designs. No external blocking capacitors are required if 0 VDC is present on the RF ports, simplifying circuit design. This attenuator is pin-compatible with older models like the PE4302, offering an upgraded performance profile with higher linearity and improved attenuation accuracy.
