Typical Applications
The HMC284AMS8G / HMC284AMS8GE is ideal for:
• Cellular/PCS Base Stations
• 2.4 GHz ISM
• 3.5 GHz Wireless Local Loop
The HMC284AMS8G & HMC284AMS8GE are low-
cost SPDT switches in 8-lead grounded base MSOP
packages. The design has been optimized to provide
high isolation with minimal insertion loss for medium
and low power applications. On-chip circuitry allows
positive voltage control operation at very low DC cur-
rents with control inputs compatible with CMOS and
most TTL logic families. In the “OFF” state, RF1 and
RF2 are non-reective.
