Self-contained board including synthesizer, VCO, and loop
filter (1 GHz to 1.7 GHz)
Designed for 1 MHz PFD frequency and 50 kHz loop
bandwidth
Accompanying software allows complete control of
synthesizer functions from a PC

GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4113HV frequency synthesizer for
phase locked loops (PLLs). The block diagram of the board is
shown in Figure 1. It contains the ADF4113HV synthesizer, a
PC connector, SMA connectors for the power supplies, and an
RF output. There is also a low-pass loop filter (50 kHz) and a
VCO (Sirenza VCO790-1500T) on board. The evaluation board
is set up for a 1 MHz PFD comparison frequency. The reference
frequency is provided by a 10 MHz TCXO. A cable is included
with the board to connect to a PC printer port. The V
supply must be driven externally.
The package also contains Windows® software to allow easy
programming of the synthesizer.

EVALUATION BOARD HARDWARE
OVERVIEW
The evaluation board is supplied with a cable for connecting to
the printer port of a PC. The board schematics are shown in
Figure 5 and Figure 6.
POWER SUPPLIES
The board is powered from a single 9 V battery, and an external
15 V source. The power supply circuitry allows the user to choose
3 V for the ADF4113HV V
supply. The default settings are 3 V for the ADF4113HV V
and 5 V for the VCO supply. The supply pin, V
externally via the SMA provided (J10) with 15 V.
It is very important to note that the ADF4113HV V
never exceed the ADF4113HV V
the device.
External power supplies can be used for the ADF4113HV V
and VCO power supplies. In this case, insert SMA connectors as
shown on the silkscreen (see Fi
ure 1).

LOCAL OSCILLATOR COMPONENTS
All components necessary for LO generation are on the board.
A 10 MHz TCXO from Fox provides the reference frequency.
The on-board loop filter is set up for a 640 μA charge pump
current and gives a loop bandwidth of 50 kHz. The VCO is
the VCO790-1500T from Sirenza. The output is available at
RF
through a standard SMA connector.
