HMC183QS24 / 183QS24E
GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 2 GHz
v02.0805
General Description
Features
Functional Diagram
Low Insertion Loss (1 GHz): 0.8dB
Integrated 3:8 Decoder
24 Lead QSOP Package
Electrical Speci cations,
TA = +25° C, For 0/-5V Control and Vee = -5V in a 50 Ohm System
Typical Applications
The HMC183QS24 / HMC183QS24E is ideal for:
• Basestation Infrastructure
The HMC183QS24 & HMC183QS24E are low-cost
non-re ective SP8T switches in 24-lead QSOP pack-
ages for use in antenna diversity, switched  lter
banks, gain/attenuation selection, and general chan-
nel multiplexing applications. A 3:8 decoder is inte-
grated 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.

Evaluation Circuit Board
The circuit board used in the  nal application should
be generated with proper RF circuit design tech-
niques. 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 eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
