General Description
Features
Functional Diagram
The HMC414MS8G & HMC414MS8GE are high effi-
ciency GaAs InGaP Heterojunction Bipolar Tran-
sistor (HBT) MMIC Power ampli ers which operate
between 2.2 and 2.8 GHz. The ampli er is packaged
in a low cost, surface mount 8 leaded package with
an exposed base for improved RF and thermal per-
formance. With a minimum of external components,
the ampli er provides 20 dB of gain, +30 dBm of satu-
rated power at 32% PAE from a +5V supply voltage.
The ampli er can also operate with a 3.6V supply. Vpd
can be used for full power down or RF output power/
current control.

5GND
Ground: Backside of package has exposed metal ground slug that must be
connected to ground thru a short path. Vias under the device are required.
6, 8 Vpd1, Vpd2
Power control pin. For maximum power, this pin should be connected to
3.6V. For 5V operation, a dropping resistor is required. A higher voltage is
not recommended. For lower idle current, this voltage can be reduced.
7Vcc
Power supply voltage for the  rst ampli er stage. An external bypass
capacitor of 330 pF is required as shown in the application schematic.

Evaluation PCB
The circuit board used in the  nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
