HMC474SC70 / 474SC70E
SiGe HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 6 GHz
v02.0814
General DescriptionFunctional Diagram
The HMC474SC70(E) is a general purpose SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT amplier covering DC to 6 GHz. This
industry standard SC70 packaged amplier can be
used as a cascadable 50 Ohm RF/IF gain stage with
up to +8 dBm output power. The HMC474SC70(E)
offers 15 dB of gain with a +20 dBm output IP3 at 850
MHz while requiring only 25 mA from a single positive
supply as low as +3V. The Darlington topology results
in reduced sensitivity to normal process variations
and excellent gain stability over temperature
while requiring a minimal number of external bias
components.
Gain: 15 dB
P1dB Output Power: +8 dBm
Output IP3: +20 dBm
Cascadable 50 Ohm I/Os
Single Supply: +3V to +10V
Industry Standard SC70 Package
Typical Applications
The HMC474SC70(E) is an ideal for:
• Cellular / PCS / 3G
• WiBro / WiMAX / 4G
• Fixed Wireless & WLAN
• CATV, Cable Modem & DBS
• Microwave Radio & Test Equipment

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
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.
