General Description
9
The HMC270MS8G & HMC270MS8GE 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 HMC284MS8G non-
reflective SPDT.

*R1 = R2 = 100 Ohm.
These are optional resistors.
List of Materials for Evaluation PCB 107949 [1]
The circuit board used in the final 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 Hittite Microwave Corporation upon
request.
