Product Summary

The HMC484MS8G is a low-cost SPDT switch in an 8-lead MSOPG package for use in transmitreceive applications which require very low distortion at high input signal power levels, through 10 watts (+40 dBm). The HMC484MS8G can control signals from DC to 3.0 GHz. The design provides exceptional intermodulation performance; > +70 dBm third order intercept at +5 volt bias. RF1 and RF2 are refl ective shorts when "OFF". On-chip circuitry of the HMC484MS8G allows single positive supply operation from +3 Vdc to +10 Vdc at very low DC current with control inputs compatible with CMOS and most TTL logic families.
