Functional Diagram
General Description
The HMC326MS8G is a high efficiency GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC driver
amplifier which operates between 3.0 and 4.5 GHz.
The amplifier is packaged in a low cost, surface mount
8 leaded package with an exposed base for improved
RF and thermal performance. The amplifier provides
21 dB of gain and +26 dBm of saturated power from
a +5.0V supply voltage. Power down capability is
available to conserve current consumption when the
amplifier is not in use. Internal circuit matching was
optimized to provide greater than 40% PAE.

The circuit board used in the final application should use RF
circuit design techniques. Signal lines should have 50 ohm
impedance while the package ground leads and exposed
paddle should be connected directly to the ground plane
similar to that shown. A sufficient number of VIA holes
should be used to connect the top and bottom ground
planes. The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board shown is
available from Hittite upon request.
