Description
The MLS9900-01035 frequency synthesizer combines a
phase locked loop circuit with a high performance
buffered VCO in an RFI screened surface mount package.
The synthesizer is optimised for mobile data service
applications with 12.5 kHz or 25 kHz RF channel
spacing. A +5V power supply and serial data input are
required.
The surface mount package used provides for electrical
shielding, ease of assembly and repeatable performance.
M/A-COM鈥檚 surface mount manufacturing techniques,
automatic assembly and electrical testing ensure a high
degree of electrical and mechanical repeatability at low
cost and in high volume. Manufacturing is carried out in
an ISO 9000 quali鏗乪d facility.
