LINEAR & POWER AMPLIFIERS - SMT
HMC450QS16G / 450QS16GE
GaAs InGaP HBT MMIC
POWER AMPLIFIER, 0.8 - 1.0 GHz
v02.0406
General Description
Features
Functional Diagram
The HMC450QS16G & HMC450QS16GE are high
efficiency GaAs InGaP HBT Medium Power MMIC
ampli ers operating between 800 and 1000 MHz. The
ampli er is packaged in a low cost, surface mount
16 lead package and offers the same pinout and
functionality as the higher band HMC413QS16G 1.6-
2.3 GHz PA. With a minimum of external components,
the ampli er provides 26 dB of gain, +40 dBm OIP3
and +28.5 dBm of saturated power from a +5V supply
voltage. The integrated power control (Vpd) can be used
for full power down or RF output power/current control.
The combination of high gain and high output IP3
make the HMC450QS16G & HMC450QS16GE ideal
linear drivers for Cellular, PCS & 3G applications.

Power Control Pin. For maximum power, this pin should be connected
to 4.0V. For 5V operation, a dropping resistor is required. A higher
voltage is not recommended. For lower idle current, this voltage can be
reduced.

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.
