| High Linearity MMIC Mixer with Integrated Local Oscillator Amplifier, 1700 - 2000 MHz Features * * * * * * Up or Down Frequency Conversion High Input IP3: 21 dBm Low LO Drive: -5 dBm to +5 dBm Very Low Current: 7 mA Single Ended Ports, 50-Ohm Impedance Small Plastic Package: SOT-26 MD57-0002 V1 Functional Schematic RF IF Description The MD57-0002 is a passive MMIC mixer with an on-chip LO buffer amplifier that allows the MD57-0002 to operate with LO drive levels of -5 dBm to +5 dBm. The MD57-0002 features single ended ports and does not require the use of external baluns. All ports are 50-ohm impedance. The MD57-0002 is ideally suited for up and down frequency convertor applications in DCS1800, PCS1900, PHS and 3G wireless communications equipment requiring low LO power, high linearity, low conversion loss and very low current consumption. The MD57-0002 is fabricated using a 0.5 micron gate length GaAs MESFET process. This process features full passivation for increased RF performance and enhanced reliability.
