HMC270MS8G / 270MS8GE
GaAs MMIC SPDT SWITCH
NON-REFLECTIVE, DC - 8 GHz
v04.0607
General Description
Features
Functional Diagram
Broadband Performance: DC - 8 GHz
Very High Isolation: 45 dB @ 6 GHz
Non-Re ective Design
Low Cost MSOP-8 Package: 14.8 mm2
Electrical Speci cations, TA = +25° C, With 0/-5V Control, 50 Ohm system
Typical Applications
The HMC270MS8G / HMC270MS8GE is ideal for
DC - 8.0 GHz applications:
• CATV
• MMDS & WirelessLAN
• Wireless Local Loop
The HMC270MS8G & HMC270MS8GE are broad-
band non-re ective 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 non-
re ective SPDT.
