HMC182S14 / 182S14E
GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 2 GHz
v03.0805
General Description
Features
Functional Diagram
Low Insertion Loss: 0.8dB
Integrated 2:4 Decoder
14 Lead SOIC Package
Electrical Speci cations,
TA = +25° C, For 0/-5V Control and Vee = -5V in a 50 Ohm System
Typical Applications
The HMC182S14 / HMC182S14E is ideal for:
• 800 - 1000 MHz Basestation
The HMC182S14 & HMC182S14E are low-cost
terminated SP4T switches in 14-lead SOIC packages
for use in antenna diversity, switched lter 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 neg-
ative 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.

Evaluation PCB
The circuit board used in the nal 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 Micro-
wave Corporation upon request.
