EVAL-ADF4212EB1
FEATURES
GENERAL DESCRIPTION
Self Contained Evaluation Board including Synthesizer,
VCOs, Loop Filters for generating GSM 1800 standards
(1700MHz to 1800MHz RF, 520MHz to 560MHz IF).
RF and IF filters designed for 20kHz Loop Bandwidth, and
200kHz Channel Spacing.
Accompanying Software allows complete control of syn-
thesizer functions from PC using Windows 95/98/NT.
Battery Operated: Choice of 3V or 5V supplies
On-Board Monitoring of Voltage and Current
Typical RF Phase Noise Performance of -84dBc/Hz @1kHz
offset.
This board is designed to allow the user to evaluate
the performance of the ADF4212 Frequency Synthe-
sizer for PLL's (Phase Locked Loops). The block
diagram of the board is shown below. It contains the
footprint for a ADF4212 synthesizer, a pc connector,
SMA connector for the reference input, power sup-
plies and RF output. There is also a loop filter and a
VCO for both the RF and IF section on board. A
cable is included with the board to connect to a pc
printer port.
Typical IF Phase Noise Performance of -90dBc/Hz @1kHz
The package also contains Windows 95/98/NT soft-
offset.
ware to allow easy programming of the synthesizer.
Typical Spurious Performance of batter than -80dBc
@200kHz offset.
