HMC239S8 / 239S8E v02.0805 Typical Applications • MMDS & WirelessLAN The HMC239S8 / HMC239S8E is ideal for: • Basestation Infrastructure • Portable Wireless Functional Diagram ED U IN NT T O SC DUC DI RO P Features Low Insertion Loss: 0.4 dB High Isolation: 35 dB Fast Switching Speed: 2ns High Input IP3: +50 dBm GaAs MMIC SPDT SWITCH DC - 2.5 GHz d fo eHMC239S8 & HMC239S8E are low-cost GaAs d The men SPDT switches in 8-lead SOIC packages. The MMIC om switch can control signals from DC to 2.5 GHz. It is Rec especially suited for low or medium power applications ot N 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”.
