HMC451LC3
v06.0514
GaAs PHEMT MMIC MEDIUM
POWER AMPLIFIER, 5 - 20 GHz
General Description
Features
Functional Diagram
The HMC451LC3 is an efficient GaAs PHEMT
MMIC Medium Power Amplier housed in a leadless
RoHS compliant SMT package. Operating between
5 and 20 GHz, the amplier provides 19 dB of gain,
+21 dBm of saturated power and 21% PAE from a
single +5V supply. This 50 Ohm matched amplier
does not require any external components and the
RF I/O’s are DC blocked, making it an ideal linear
gain block or driver for HMC SMT mixers. The
HMC451LC3 allows the use of surface mount
manufacturing techniques.
Gain: 19 dB
Saturated Power: +21 dBm @ 21% PAE
Output IP3: +30 dBm
Single Supply: +5V @ 114 mA
50 Ohm Matched Input/Output
RoHS Compliant 3 x 3 mm SMT package
Electrical Specications, TA = +25° C, Vdd1 = Vdd2 = +5V
Typical Applications
The HMC451LC3 is ideal for use as a medium power
amplier for:
• Microwave Radio & VSAT
• Military & Space
• Test Equipment & Sensors
• Fiber Optics
• LO Driver for HMC Mixers

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 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.
