SiGe HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 5 GHz
v03.0810
General DescriptionFunctional Diagram
The HMC479MP86 & HMC479MP86E are SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT ampli ers covering DC to 5 GHz. This
Micro-P packaged ampli er can be used as a
cascadable 50 Ohm RF/IF gain stage as well as a LO
or PA driver with up to +21 dBm output power. The
HMC479MP86(E) offers 15 dB of gain with a +34 dBm
output IP3 at 850 MHz while requiring only 72 mA from
a single positive supply. The Darlington feedback pair
used results in reduced sensitivity to normal process
variations and excellent gain stability over temperature
while requiring a minimal number of external bias
components.
P1dB Output Power: +18 dBm
Gain: 15 dB
Output IP3: +34 dBm
Cascadable 50 Ohm I/Os
Single Supply: +5V to +12V
Included in the HMC-DK001 Designer’s Kit
Typical Applications
The HMC479MP86 / HMC479MP86E is an ideal RF/
IF gain block & LO or PA driver:
• Cellular / PCS / 3G
• Fixed Wireless & WLAN
• CATV, Cable Modem & DBS
• Microwave Radio & Test Equipment
Electrical Speci cations, Vs= 8.0 V, Rbias= 51 Ohm, TA = +25° C

Evaluation PCB
The circuit board used in the application should
use RF circuit design techniques. Signal lines sho-
uld have 50 Ohm impedance while the package
ground leads 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.
