GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4113 frequency synthesizer for phase
locked loops (PLLs). The block diagram of the board is shown
in Figure 1. It contains the ADF4113 synthesizer, a PC connector, an SMA connector for the reference input, power
supplies, and an RF output. There is also a loop filter (20 kHz
bandwidth) and a VCO on board. A cable is included with the
board to connect to a PC printer port.
The package also contains Windows® software to allow easy
programming of the synthesizer.

EVALUATION BOARD HARDWARE
HARDWARE DESCRIPTION
The evaluation board is supplied with a cable for connecting to
the printer port of a PC. The silkscreen and cable diagram for
the evaluation board are shown in Figure 2 and Figure 3,
respectively. The board schematic is shown in Figure 5 and
Figure 6.
damage the device. All components necessary for LO generation
are on board. The 10 MHz TCXO from Vectron provides the
necessary reference input. The PLL is made up of the ADF4113, a
passive loop filter (20 kHz bandwidth), and the VCO 190-1750
from Vari-L. The output is available at RF
through a

standard SMA connector. Users can use their own power
supplies and reference input. In this case, they need to insert
SMA connectors as shown in Figure 2 and Figure 3.
Loop filter components include
C1 = 1.0 nF, C2 = 10 nF, C3 = 120 pF
R1 = 3.9 kΩ, R2 = 20 kΩ
