Description
The MLS9108-00766 synthesizer design integrates a high performance buffered VCO, PLL circuit and discrete loop filter in a
surface mount package. The SMT packaging provides electrical
IDENT
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 with 70 MHz IF,
30 kHz step size and low phase noise.
M/A-COM synthesizers are manufactured in an ISO 9001 certified facility, incorporating surface mount assembly and automated
electrical testing. This ensures consistent electrical performance
and quality over volume production quantities.

1. Exceeding these limits may cause permanent damage.
2. Static sensi tive, observe appropri ate precautions.
3. An external series resistor and bypass capacitor will allow operation at higher supply voltage and will improve power supply decoupling and noise suppres sion.
Ordering Information
Synthesizers are available in either tape and reel or tube packaging. To order devices in tape and reel requires the suffix TR be
added to the part number, i.e. MLS9108-00766TR. Quantity 500
per 13 inch reel, see Application Note M2030.
