RoHS Compliant Low Cost MMIC Mixer with Local Oscillator Amplifier 0.8 GHz - 1.0 GHz Functional Schematic Features • • • • • • • MAMX-008611 V1 -5 to +5 dBm LO Drive Level High Isolation, 28 dB LO to RF Lead Free SOT-26 package 100% Matte Tin Plating over Copper Halogen-Free “Green” Mold Compound 260°C Re-flow Compatible RoHS Compliant Version of MD57-0001 Description The MAMX-008611 is a floating FET mixer with an on-chip LO amplifier. The LO drive for the MAMX008611 can range from –5 to +5 dBm without severely impacting the mixer’s performance. The MAMX-008611 is ideally suited for cellular band communications handsets’ that can provide only minimal amounts of LO drive. Typical applications include frequency up/down conversion and IQ modulation and demodulation in digital receivers and transmitters. Pin Configuration Pin No. Pin Name Description 1 RF Port RF Input/Output 2 Bias LO Amplifier Bias Resistor 3 LO Port LO Input 4 VDD LO Amplifier VDD The MAMX-008611 utilizes a patented “floatingFET” architecture. The on-chip LO amplifier allows the MAMX-008611 to operate with as little as –5 dBm of LO drive making it an ideal choice for low power portable designs. The MAMX-008611 is fabricated using M/A-COM’s 0.5 micron low noise GaAs MESFET process. This process features full passivation for increased performance and reliability. The MAMX-008611 is 100% RF tested to ensure superior performance specification compliance. 5 GND Ground 6 IF Port IF Input/Output Absolute Maximum Ratings 2,3,4,5 Parameter Absolute Maximum 4 Input RF/IF Power Input LO Power4 Ordering Information1 Operating Voltages Part Number Package MAMX-008611-000000 SOT-26 MAMX-008611-TR1000 1000 piece reel MAMX-008611-TR3000 3000 piece reel 1.
