HMC182S14 / 182S14E
v03.0805
GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 2 GHz
Typical Applications
The HMC182S14 / HMC182S14E is ideal for: • 800 - 1000 MHz Basestation
Features
Low Insertion Loss: 0.8dB 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. See positive bias / TTL SP4T HMC241QS16.

The circuit board used in the final application should be generated with proper RF circuit design techniques. Signal lines at the RF port should have 50 ohm impedance and the package ground leads should be connected directly to the ground plane similar to that shown above. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request.
