The MLS9033-00766 synthesizer design integrates a high performance buffered VCO, PLL circuit and discrete loop filter in a surface mount package. The SMT packaging provides electrical shielding, easy PCB assembly and repeatable performance. The synthesizer is designed for use in CDMA base stations and is optimised for coverage of the cellular Rx band, 70 MHz IF, 10 kHz, step size and low phase noise.
