HMC182S14 / 182S14E v03.0805 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 2 GHz Typical Applications Features The HMC182S14 / HMC182S14E is ideal for: Low Insertion Loss: 0.8dB • 800 - 1000 MHz Basestation Integrated 2:4 Decoder 14 Lead SOIC Package Functional Diagram General Description The HMC182S14 & HMC182S14E are low-cost terminated SP4T switches in 14-lead SOIC packages for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. The switch can control signals up to 2 GHz. A 2:4 decoder is integrated on the switch, requiring only 2 control lines and a negative bias to select each RF path. The 2:4 decoder replaces 4 to 8 control lines normally required by GaAs SP4T switches. The HMC182S14(E) are drop-in replacements for the HMC165S14 in applications requiring low “off state” VSWR.
