| Dual-Band/Triple-Mode Downconverter 869 - 893 MHz and 1930 - 1990 MHz Features * * * * * * Highly Integrated Downconverter Operates over 2.8 V to 5 V Supply Voltage Dual-Band and Triple-Mode Operation High Linearity, IP3 = 10 dBm typical Adjustable Gain and IP3 4 mm 20-Lead PQFN Plastic Package MADCSM0001 V2 Functional Block Diagram MODE SEL VDD CELL IFA IN MODE SEL CELL VDD CELL SRC 1 CELL MIX GND CELL IF OUT1 CELL IF OUT2 GND PCS IF OUT PCS SRC PCS LO IN GND PCS VDD GND CELL LO IN Description M/A-COM's MADCSM0001 is a downconverter suitable for Dual-Band and Triple-Mode Operation. The MADCSM0001 has a 50-ohm matched input, consumes low DC power and incorporates an on-chip switch that determines CDMA and AMPS mode select. The designer can tailor the linearity and gain performance of the MADCSM0001 according to the system needs. The MADCSM0001 is ideally suited for wireless applications where low noise, low current and high linearity are important features. The MADCSM0001 is fabricated using M/A-COM's 0.5-micron low noise E/D GaAs MESFET process. The process features full passivation for increased performance and reliability.
