GENERAL DESCRIPTION

The HMC1055 is a low cost, gallium arsenide (GaAs), single-

pole, single-throw (SPST) switch in a surface-mount LFCSP

package. This switch offers low insertion loss, high isolation,

and exceptional third-order intermodulation performance that

make it ideal for many cellular and wireless infrastructure

applications from 0.5 GHz to 4.0 GHz.

The HMC1055 operates with single positive supply voltage and

a single positive control voltage at very low dc currents. RF1 is

reflective open, whereas RF2 is terminated to 50 Ω in the off

state.
