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 re-
peatable performance. The synthesizer is designed for use in wire-
less base stations.
M/A-COM synthesizers are manufactured in an ISO9001 certified
facility, incorporating surface mount assembly and automated elec-
trical testing. This ensures consistent electrical performance and
quality over volume production quantities.
