HMC241LP3

HMC241LP3 / 241LP3E v01.0905 GaAs MMIC SP4T NON-REFLECTIVE SWITCH, DC - 4 GHz Typical Applications The HMC241LP3 / HMC241LP3E is ideal for: • Base Stations & Repeaters • WLAN, WiMAX & WiBro • CATV / DBS • Test Equipment 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 Functional Diagram General Description The HMC241LP3 & HMC241LP3E are general purpose non-reflective SP4T switches in low cost leadless surface mount packages. Covering DC - 4 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. 10 SWITCHES - SMT Electrical Specifi cations, TA = +25° C, For TTL Control and Vdd = +5V in a 50 Ohm System Parameter Frequency DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 4.0 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 4.0 GHz “On State” RF1-4 “Off State” DC - 2.5 GHz DC - 4.0 GHz 0.3 - 4.0 GHz 0.3 - 4.0 GHz 0.3 - 4.0 GHz 0.3 - 4.0 GHz tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 40 100 ns ns 40 38 35 25 Min.
