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.

The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF ports should have
50 Ohm impedance and the package ground leads
and exposed ground paddle should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above
is available from Analog Devices Inc. upon request.
