HMC270AMS8GE v02.0316 SWITCHES - SPDT - SMT GaAs MMIC SPDT SWITCH NON-REFLECTIVE, DC -8 GHz Typical Applications Features The HMC270AMS8GE is ideal for DC - 8.0 GHz applications: Broadband Performance: DC - 8 GHz * CATV Non-Reflective Design * MMDS & WirelessLAN Low Cost MSOP-8 Package: 14.8 mm2 Very High Isolation: 45 dB @ 6 GHz * Wireless Local Loop Functional Diagram General Description The HMC270AMS8GE are broad-band non-reflective GaAs SPDT switches in 8 lead MSOP grounded base surface mount plastic packages. Covering DC to 8 GHz, the switch offers excellent isolation from 70 to 35 dB. The negative control voltage of -5 volts allows operation down to DC. If positive control is required along with high isolation, see the DC to 3.5 GHz HMC284AMS8GE non-reflective SPDT.
