SKY12355-337LF

Attenuators Overview

The SKY12355-337LF is a high-performance GaAs pHEMT two-bit digital attenuator manufactured by Skyworks Solutions. It operates within a frequency range of 350 MHz to 4 GHz and provides an attenuation range of 6 dB to 18 dB with a typical insertion loss of 0.6 dB at 2.5 GHz. The device features integrated drivers for fast settling times and supports control voltages from 1.8 V to 5 V. Packaged in a compact 12-TFQFN exposed pad, it maintains a 50 Ohm impedance and functions reliably across temperatures from -40°C to +85°C.

Attenuators Feature Summary
