The HMC224MS8 is a low-cost SPDT switch in an 8-lead MSOP package for use in transmit-receive applications. The device can control signals from 5.0 to 6.0 GHz and is especially suited for 5.2 GHz UNII and 5.8 GHz ISM applications with only 1.2 dB loss. The design provides exceptional power handling performance; input P1dB = +33dBm at 5 Volt bias. RF1 or RF2 is a reflective short when "Off". On-chip circuitry allows single positive supply operation at very low DC current with control inputs compatible with CMOS and most TTL logic families. No DC blocking capacitors are required on RF I/O ports. HMC224MS8 is especially suited for PCMCIA wireless LAN applications.
