Typical Applications

The HMC182S14 / HMC182S14E is ideal for:

• 800 - 1000 MHz Basestation

The HMC182S14 & HMC182S14E are low-cost termi-

nated SP4T switches in 14-lead SOIC packages for

use in antenna diversity, switched filter banks, gain/

attenuation selection, and general channel multiplex-

ing applications. The switch can control signals up to 2

GHz. A 2:4 decoder is integrated on the switch, requir-

ing 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 & HMC182S14E are drop-in replace-

ments for the HMC165S14 in applications requiring

low “off state” VSWR. See positive bias/TTL SP4T

HMC241QS16.
