MD57-0001 Low Cost MMIC Mixer with Local Oscillator Amplifier 0.8 - 1.0 GHz Features Rev. V3 Functional Schematic • -5 to +5 dBm LO Drive Level • High Isolation, 28 dB LO to RF • SOT-26 package Description The MD57-0001 is a floating FET mixer with an onchip LO amplifier. The LO drive for the MD57-0001 can range from –5 to +5 dBm without severely impacting the mixer’s performance. The MD57-0001 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. The MD57-0001 utilizes a patented “floating-FET” architecture. The on-chip LO amplifier allows the MD57-0001 to operate with as little as –5 dBm of LO drive making it an ideal choice for low power portable designs. The MD57-0001 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 MD57-0001 is 100% RF tested to ensure superior performance specification compliance.
