A
= +25° C, For TTL Control and Vdd = +5V in a 50 Ohm system
Typical Applications
The HMC253ALC4 is ideal for:
• Basestations & Repeaters
• WiMAX/WiBro & Fixed Wireless
• Cellular/3G Infrastructure
• CATV/DBS
• Military & Hi-Rel
The HMC253ALC4 is a non-reective 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 HMC253ALC4 SP8T will replace multiple
congurations of SP4T and SPDT MMIC switches.
