Overview

Description

The ISL71934M is a radiation tolerant, low insertion loss, 50Ω SP2T absorptive RF switch designed for a multitude of wireless and communications applications. This device covers a broad frequency range from 50MHz to 10GHz. In addition to providing low insertion loss, the device delivers high linearity and high isolation performance while providing a constant 50Ω termination to the unused input. The ISL71934M features patented Constant Impedance Technology, which reduces transients during switching events, allowing the impedance match to stay constant.

The ISL71934M is rated for Total Ionizing Dose (TID) up to 30krad(Si) and Single Event Latch-up and Burnout up to 43MeV∙cm²/mg. The device operates over the full military temperature range of -55 °C to +125 °C and uses a NiPdAu plated µPPF roughened lead frame.
