| HMC241LP3 / 241LP3E v01.0905 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 4.0 GHz Typical Applications The HMC241LP3 / HMC241LP3E is ideal for: * Base Stations & Repeaters * WLAN, WiMAX & WiBro * CATV / DBS Features High Isolation: 43 dB @ 2 GHz Low Insertion Loss: 0.7 dB @ 2 GHz Single Positive Supply: Vdd = +5V Integrated 2:4 TTL Decoder 3x3 mm SMT Package 8 SWITCHES - SMT * Test Equipment Functional Diagram General Description The HMC241LP3 & HMC241LP3E are general purpose non-reflective SP4T switches in low cost leadless surface mount packages. Covering DC - 4.0 GHz, this switch offers high isolation and has a low insertion loss of 0.7 dB at 2 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility. A 2:4 decoder is integrated on the switch requiring only 2 control lines and a positive bias to select each path, replacing 4 to 8 control lines normally required by GaAs SP4T switches.
