HMC183QS24 / 183QS24E
v02.0805
GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 2 GHz
Typical Applications
Features
The HMC183QS24 / HMC183QS24E is ideal for:
Low Insertion Loss (1 GHz): 0.8dB
• Basestation Infrastructure
Integrated 3:8 Decoder
TE
24 Lead QSOP Package
Functional Diagram
General Description
The HMC183QS24 & HMC183QS24E are low-cost
non-reflective SP8T switches in 24-lead QSOP packages for use in antenna diversity, switched filter
banks, gain/attenuation selection, and general channel multiplexing applications. A 3:8 decoder is integrated on the switch, requiring only 3 control lines with
a negative bias to select an RF path. The 3:8 decoder
replaces 16 control lines normally required by GaAs
SP8T switches. Switch outputs are terminated when
“off”. The QSOP24 package occupies the same area
as a 14-lead SOIC. See positive bias/TTL version
HMC253QS24.

103704 Evaluation PCB
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 and
package bottom 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.
