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.

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.

Environmental Specifications

Devices are designed to function over the operating temperature
range (T

OP

) of -40°C to +85°C and after exposure to the shock,
vibration, thermal shock and moisture conditions typically encoun­tered in base station and other infrastructure environments.

Typical Performance

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.
