v00.0504 HMC471MS8G SiGe HBT DUAL CHANNEL GAIN BLOCK MMIC AMPLIFIER, DC - 5.0 GHz AMPLIFIERS - SMT 8 Typical Applications Features The HMC471MS8G is a dual RF/IF gain block & LO or PA driver: +20 dBm P1dB Output Power • Cellular / PCS / 3G Output IP3: +34 dBm • Fixed Wireless & WLAN Supply (Vs): +6V to +12V • CATV, Cable Modem & DBS 14.9 mm2 Ultra Small 8 Lead MSOP • Microwave Radio & Test Equipment 20 dB Gain General Description The HMC471MS8G is a SiGe HBT Dual Channel Gain Block MMIC SMT amplifier covering DC to 5 GHz. This versatile product contains two gain blocks, packaged in a single 8 lead plastic MSOP, for use as either separate cascadable 50 Ohm RF/IF gain stages, LO or PA drivers or with both amplifiers combined utilizing external 90° hybrids to create a high linearity driver amplifier. Each amplifier in the HMC471MS8G offers 20 dB of gain, +20dBm P1dB with a +34 dBm output IP3 at 850 MHz while requiring only 80 mA from a single positive supply. The combined dual amplifier circuit delivers up to +21 dBm P1dB with +36dBm OIP3 for specific application bands through 4 GHz.

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. ** Circuit Board Material: Rogers 4350 * Reference this number when ordering complete evaluation PCB.
