HMC270MS8G
GaAs MMIC SPDT SWITCH
NON-REFLECTIVE, DC - 8.0 GHz
Features
Broadband Performance: DC - 8 GHz
Very High Isolation: 45 dB @ 6 GHz
Non-Refl ective Design
Low Cost MSOP-8 Package: 14.8 mm
General Description
The HMC270MS8G is a broadband non-refl ective
GaAs SPDT switch in an 8 lead MSOP grounded
base surface mount plastic package. 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-refl ective
SPDT.
