Typical Applications
The HMC210MS8 is a miniature absorptive voltage
variable attenuator in an 8-lead MSOP package.
The device operates with a positive supply voltage
(+2.5V), and a positive control voltage. A unique
feature is the high third order intercept point for all
attenuation states. Operation up to 2.3 GHz is pos-
sible with a reduced attenuation range of 31 dB.
The HMC210MS8 is ideal for:

Evaluation Circuit Board
v01.0801
HMC210MS8
GaAs MMIC VOLTAGE-VARIABLE
ATTENUATOR, 1.5 - 2.3 GHz
The circuit board used in the fi nal application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF ports should be 50
ohm impedance and the package ground leads and
package bottom should be connected directly to the
PCB RF ground plane, similar to that shown above.
The evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
