Synthesizer , SMT 1920 -- 2000 MHz, 100 & 200 kHz
Features
Fully Integrated VCO, PLL, Loop Filter High Performance, Low Cost Miniature SMT Package (LSM6)
MASYVS0006-1950
Rev: F
Description
This synthesizer design integrates a high performance VCO, PLL, IC and discrete loop filter in a surface mount package. This SMT package provides electrical shielding, easy PCB assembly and repeatable performance. The synthesizer is designed for use in wireless base stations. M/A-COM synthesizers are manufactured in an ISO9001 certified facility, incorporating surface mount assembly and automated electrical testing. This ensures consistent electrical performance and quality over volume production quantities.
