HMC270MS8G

HMC270MS8G / 270MS8GE v04.0607 GaAs MMIC SPDT SWITCH NON-REFLECTIVE, DC - 8.0 GHz Typical Applications The HMC270MS8G / HMC270MS8GE is ideal for DC - 8.0 GHz applications: • CATV • MMDS & WirelessLAN • Wireless Local Loop Features Broadband Performance: DC - 8 GHz Very High Isolation: 45 dB @ 6 GHz Non-Reflective Design Low Cost MSOP-8 Package: 14.8 mm2 9 SWITCHES - SMT Functional Diagram General Description The HMC270MS8G & HMC270MS8GE are broadband 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 HMC284MS8G nonreflective SPDT.
