HMC239S8 / 239S8E v02.0805 GaAs MMIC SPDT SWITCH DC - 2.5 GHz D E U N I T N O T C C S U I D D O PR Typical Applications Features The HMC239S8 / HMC239S8E is ideal for: Low Insertion Loss: 0.4 dB • MMDS & WirelessLAN High Isolation: 35 dB • Basestation Infrastructure Fast Switching Speed: 2ns • Portable Wireless High Input IP3: +50 dBm Functional Diagram General Description r Ne w fo d e d HMC239S8 & HMC239S8E are low-cost GaAs enThe m MMIC SPDT switches in 8-lead SOIC packages. The m o c switch can control signals from DC to 2.5 GHz. It is Re t especially suited for low or medium power applications o N which require extremely fast switching with SWITCHES - SPDT - SMT 14 minimal insertion loss. The two control voltages require a minimal amount of DC current which is optimal for battery powered radio systems. RF1 and RF2 are reflective shorts when “Off”.
