    UMTS Base Station Receiver Fits in Half-Inch Square
    Docket ↓
    design features UMTS Base Station Receiver Fits in Half-Inch Square
    Douglas Stuetzle and Todd Nelson How much integration is possible while still meeting
    macrocell base station performance requirements? Process
    technology dictates that certain key functions are produced
    in specific processes: GaAs and SiGe in the RF realm,
    fine-line CMOS for high speed ADCs, and high-Q filters
    cannot be implemented well in semiconductor materials.
    Yet the market continues to demand higher integration.
    With that in mind, Linear Technology
    has applied system-in-package (SiP)
    technology to build a receiver occupying about one-half square inch (just over
    3cm2). The boundaries of the receiver
    are the 50О© RF input, the 50О© LO input,
    the ADC clock input and the digital
    ADC output. This leaves the low noise
    amplifier (LNA) and RF filtering to be
    added for the input, LO and clock generation, and digital processing of the digital
    output. Within the 15mm Г— 22mm package is a signal chain utilizing SiGe high frequency components, discrete passive filtering and fine-line CMOS ADCs.
    This article presents a design analysis for
    the LTM9004 ВµModuleВ® receiver implementing a direct conversion receiver.
