HMC253ALC4 v00.0413 GaAs MIMIC SP8T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Typical Applications Features The HMC253ALC4 is ideal for: Ceramic, RoHS Compliant 4x4 mm SMT Package Basestations & Repeaters Non-Reflective Topology WiMAX/WiBro & Fixed Wireless Low Insertion Loss: 1.6 dB Cellular/3G Infrastructure Single Positive Supply: Vdd = +5V CATV/DBS Integrated 3:8 TTL/CMOS Decoder: 0/+3V Military & Hi-Rel Functional Diagram General Description The HMC253ALC4 is a non-reflective 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 configurations of SP4T and SPDT MMIC switches. Electrical Specifications, T = +25 C, For TTL Control and Vdd = +5V in a 50 Ohm system A Parameter Frequency Min. Typ. Max.
