HMC239AS8 / 239AS8E v00.0311 Switches - SPDT - SMT GaAs MMIC SPDT SWITCH DC - 2.5 GHz Typical Applications Features The HMC239AS8 / HMC239AS8E is ideal for: Low Insertion Loss: 0.4 dB * MMDS & WirelessLAN High Isolation: 35 dB * Basestation Infrastructure Fast Switching Speed: 2 ns * Portable Wireless High Input IP3: +50 dBm Functional Diagram General Description The HMC239AS8 & HMC239AS8E 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".
