Description
The MLS9208-01800 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 PCS CDMA base stations and is optimised for 50 kHz step size and low phase noise and spurious performance. 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.

Environmental Specifications
Devices are designed to function over the operating temperature range (TOP) of -40C to +85C and after exposure to the shock, vibration, thermal shock and moisture conditions typically encountered in base station and other infrastructure environments.
1. Exceeding these limits may cause permanent damage. 2. Static sensitive, observe appropriate handling precautions. 3. An external series resistor and bypass capacitor will allow operation at higher supply voltage and will improve power supply decoupling and noise suppression.
Ordering Information
Synthesizers are available in either tape and reel or tube packaging. To order devices in tape and reel requires the suffix TR to be added to the part number, i.e. MLS9208-01800TR. Quantity 500 per 13 inch reel, see Application Note M2030.
