HMC239S8 / 239S8E v02.0805 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 The HMC239S8 & HMC239S8E are low-cost GaAs MMIC SPDT switches in 8-lead SOIC packages. The switch can control signals from DC to 2.5 GHz. It is especially suited for low or medium power applications which require extremely fast switching with 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”.
