General Description
Features
Functional Diagram
The HMC407MS8G & HMC407MS8GE are high
efficiency GaAs InGaP Heterojunction Bipolar
Transistor (HBT) MMIC Power ampli ers which
operate between 5 and 7 GHz. The ampli er requires
no external matching to achieve operation and is
thus truly 50 Ohm matched at input and output. The
ampli er is packaged in a low cost, surface mount
8 leaded package with an exposed base for im-
proved RF and thermal performance. The ampli er
provides 15 dB of gain, +29 dBm of saturated power
at 28% PAE from a +5V supply voltage. Power down
capability is available to conserve current consum-
ption when the ampli er is not in use.

Pin Number Function Description Interface Schematic
1Vcc1
Power supply voltage for the rst ampli er stage. An external bypass capacitor
of 330 pF is required as shown in the application schematic.
2Vpd
Power control pin. For maximum power, this pin should be connected to 5V. A
higher voltage is not recommended. For lower die current, this voltage can be
reduced.
3, 6, 7 GND 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.
4RFIN This pin is AC coupled
and matched to 50 Ohms.
5RFOUT This pin is AC coupled
and matched to 50 Ohms.
8Vcc2
Power supply voltage for the output ampli er stage. An external bypass
capacitor of 330 pF is required. This capacitor should be placed no more than
20 mils form package lead.

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 connected
directly to the ground plane similar to that shown. A
sufficient number of via holes should be used to con-
nect the top and bottom ground planes. The evalua-
tion board should be mounted to an appropriate heat
sink. The evaluation circuit board shown is available
from Hittite upon request.
