HMC253LC4
v02.0414
GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 3.5 GHz
General Description
Features
Functional Diagram
Ceramic, RoHS Compliant 4x4mm SMT Package
Non-Reective Topology
Low Insertion Loss: 1.2 dB
Single Positive Supply: Vdd = +5V
Integrated 3:8 TTL/CMOS Decoder: 0/+3V
Electrical Specications,
TA = +25° C, For TTL Control and Vdd = +5V in a 50 Ohm system
Typical Applications
The HMC253LC4 is ideal for:
• Basestations & Repeaters
• WiMAX/WiBro & Fixed Wireless
• Cellular/3G Infrastructure
• CATV/DBS
• Military & Hi-Rel
The HMC253LC4 is a non-reective SP8T switch in
a leadless RoHS compliant 4x4 mm ceramic SMT
package featuring wideband operation from DC to
3.5 GHz. The switch offers a single positive bias and
true TTL/CMOS compatibility enabling it to operate
with 0/+3V control and a +5V supply. A 3:8 decoder
is integrated on the switch requiring only 3 control
lines and a positive bias to select each path. The
HMC253LC4 SP8T will replace multiple congurations
of SP4T and SPDT MMIC switches.

Evaluation Circuit Board
The circuit board used in the application should be
generated with proper RF circuit design techniques.
Signal lines at the RF ports should have 50 ohm
impedance while the package ground leads should be
connected directly to the ground plane similar to that
shown above. A sufficient number of via holes should
be used to connect the top and bottom ground planes.
The evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
