LINEAR & POWER AMPLIFIERS - SMT
HMC408LP3 / 408LP3E
GaAs InGaP HBT MMIC 1 WATT
POWER AMPLIFIER, 5.1 - 5.9 GHz
v03.0705
General Description
Features
Functional Diagram
The HMC408LP3 & HMC408LP3E are 5.1 - 5.9 GHz
high efficiency GaAs InGaP Heterojunction Bipolar
Transistor (HBT) Power Ampli er MMICs which offer
+30 dBm P1dB. The ampli er provides 20 dB of gain,
+32.5 dBm of saturated power, and 27% PAE from a
+5V supply voltage. The input is internally matched
to 50 Ohms while the output requires a minimum of
external components. Vpd can be used for full power
down or RF output power/current control. The ampli er
is packaged in a low cost, 3x3 mm leadless surface
mount package with an exposed base for improved
RF and thermal performance.

Pin Descriptions
Pin Number Function Description Interface Schematic
1Vpd
Power control pin. For maximum power, this pin should be
connected to 5V. A higher voltage is not recommended. For
lower idle current, this voltage can be reduced.

14 Vcc2
Power supply voltage for the second ampli er stage. Exter-
nal bypass capacitors and pull up choke are required as
shown in the application schematic.
16 Vcc1
Power supply voltage for the  rst ampli er stage. External
bypass capacitors are 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.
