Typical Applications
The HMC270AMS8GE is ideal for
DC - 8.0 GHz applications:
• CATV
• MMDS & WirelessLAN
• Wireless Local Loop
The HMC270AMS8GE are broad-band non-reective
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-reective SPDT.
