• Rohs Status: RoHS non-compliant

HARDWARE DESCRIPTION
The evaluation board comes with a cable for connecting to the
printer port of a PC. The silk screen and cable diagram for the
evaluation board are shown below. The board schematic is
shown on pages 4 & 5.
The board is powered from a single 9V battery. All components
necessary for LO generation are catered for on-board. A 10
MHz TCXO from Fox provides the necessary reference input.
Otherwise an external reference signal can be connected via J3.
The PLL comprises the ADF4360-0BCP and a passive loop
filter. The VCO output from RF
standard SMA connector J1, and the complementary RF
VCO output is available from J2.

If the user wishes they may use their own power supplies using
connectors J4 & J5 as shown on the silkscreen. Hardware power
down using the CE pin can be controlled by inserting an SMA
connector into J6 and removing R12.
The on board filter is a third order passive low pass filter. This
contains three capacitors (C13, C14 & C15) plus two resistors
(R10 & R11). The footprint for R10 is located on the underside
of the board. The design parameters for the loop filter are for a
centre frequency of 2500 MHz, PFD frequency of 200 kHz and
a low pass filter bandwidth of 10 kHz. To design a filter for
different frequency setups, please use ADIsimPLL.
RF OUTPUT STAGES
The output stage of the board contains a tuned load for the
particular frequency of operation. The particular network
inserted in the board is optimized for 2500 MHz operation.
This consists of a 4.7 nH shunt inductor, a 10 pF series
capacitor and a zero ohm resistor. If in doubt use a 50 Ohm
resistor instead of the shunt inductor, a 100 pF bypass capacitor
and a series zero ohm resistor. It is very important that the
same components be placed on the RF
also it is essential that BOTH outputs be terminated with 50
Ohm loads. Otherwise the output power will not be optimum,
and in some cases the part may malfunction.
