| HMC308 / 308E v05.1107 GENERAL PURPOSE 100 mW GaAs MMIC AMPLIFIER, 0.8 - 3.8 GHz Features Gain: 18 dB P1dB Output Power: +17 dBm@ +5V Single Supply: +3V or +5V No External Components Integrated DC Blocks Ultra Small Package: SOT26 Typical Applications 5 DRIVER & GAIN BLOCK AMPLIFIERS - SMT Broadband or Narrow Band Applications: * Cellular/PCS/3G * Fixed Wireless & Telematics * Cable Modem Termination Systems * WLAN, Bluetooth & RFID Functional Diagram General Description The HMC308 & HMC308E are low cost MESFET MMIC amplifiers that operate from a single +3 to +5V supply from 0.8 to 3.8 GHz. The surface mount SOT26 amplifier can be used as a broadband amplifier stage or used with external matching for optimized narrow band applications. With Vdd biased at +5V, the HMC308 & HMC308E offers 18 dB of gain and +20 dBm of saturated output power while requiring only 53 mA of current. This amplifier is ideal as a driver amplifier for transmitters or for use as a local oscillator (LO) amplifier to increase drive levels for passive mixers. The amplifier occupies 0.014 in2 (9 mm2), making it ideal for compact radio designs.
