General Description
Functional Diagram The HMC471MS8G & HMC471MS8GE are SiGe HBT
Dual Channel Gain Block MMIC SMT ampli ers cov-
ering DC to 5 GHz. These versatile products contain
two gain blocks, packaged in a single 8 lead plas-
tic MSOP, for use as either separate cascadable 50
Ohm RF/IF gain stages, LO or PA drivers or with both
ampli ers combined utilizing external 90° hybrids to
create a high linearity driver ampli er. Each ampli-
er in the HMC471MS8G(E) offers 20 dB of gain,
+20 dBm P1dB with a +34 dBm output IP3 at 850
MHz while requiring only 80 mA from a single positive
supply. The combined dual ampli er circuit delivers
up to +21 dBm P1dB with +36 dBm OIP3 for speci c
application bands through 4 GHz.
P1dB Output Power: +20 dBm
Gain: 20 dB
Output IP3: +34 dBm
Supply (Vs): +6V to +12V
14.9 mm2 Ultra Small 8 Lead MSOP
Typical Applications
The HMC471MS8G / HMC471MS8GE is a dual 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= 39 Ohm, TA = +25° C
Note: Data taken with broadband bias tee on device output. All speci cations refer to a single ampli er.

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 package bottom 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.
