SiGe HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 4 GHz

General Description
Functional Diagram
The HMC478MP86 & HMC478MP86E are SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT ampli ers covering DC to 4 GHz. This
Micro-P packaged ampli er can be used as a cas-
cadable 50 Ohm RF/IF gain stage as well as a
LO or PA driver with up to +20 dBm output power.
The HMC478MP86(E) offers 22 dB of gain with a
+32 dBm output IP3 at 850 MHz while requiring only
62 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: 22 dB
Output IP3: +32 dBm
Cascadable 50 Ohm I/Os
Single Supply: +5V to +8V
Robust 1,000V ESD, Class 1C
Included in the HMC-DK001 Designer’s Kit
Typical Applications
The HMC478MP86 / HMC478MP86E 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= 5V, Rbias= 18 Ohm, TA = +25° C
