General Description
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 possible with a reduced attenuation range of 31 dB.

The circuit board used in the final application should be generated with proper RF circuit design techniques. 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.
