SKY12345-362LF

Attenuators Overview

The SKY12345-362LF is a GaAs FET five-bit digital attenuator designed for frequencies between 700 MHz and 4 GHz. It features a serial-to-parallel driver and operates with a 5 V supply voltage. The device provides 15.5 dB of attenuation with a 0.5 dB LSB step size, achieving an insertion loss of 2.7 dB at 1 dB attenuation. It supports 32 dBm power handling and functions within a -40°C to +85°C temperature range in a QFN-24 package.
