FEATURES

GE NE RAL D E SC RIP T IO N

Self-Contained Board including Synthesizer, RF VCO and

loop filter for generating frequencies of 2.3GHz to

2.4GHz and IF VCO and loop filter for generating fre-

quencies of 700MHz to 850MHz

T his board is designed to allow the user to evaluate

the performance of the ADF4213 Dual Frequency

Synthesizer for PLL's (Phase Locked Loops). T he

block diagram of the board is shown below. It con-

tains the ADF4213 synthesizer, a pc connector, SMA

connector for the reference input, power supplies and

RF and IF output. T here is also a loop filter for both

sides (20kHz bandwidth) and an RF and IF VCO on

board. A cable is included with the board to connect

to a pc printer port.

Designed for 20kHz Loop Bandw idth

Accom panying Softw are allow s com plete controlofsynthesizer

functions from PC using Window s 95/ 98/ NT

Battery Operated: Choice of 3V or 5V supplies

On Board Monitoring of Current and Voltage.

Typical Phase Noise Perform ance of -83.5dBc/ Hz (RF side)

@ 1kHz offset

T he package also contains windows software to allow

easy programming of the synthesizer.

Typical Phase Noise Perform ance of -90dBc/ Hz (IF side) @

1kHz offset.

T his helps the user pick the optimum synthesizer settings

for power consumption and also provides an alert if the

battery voltage is too low to sustain the required 3V or 5V

for the board supply.

T he RF loop component values are for a 2.35GHz output,

with 5mA CP current, VCO 190-2350T , 200kH z channel

spacing and 20kH z loop band-width.

T he component values for the IF side are for a 760MHz

output, 5mA CP current, VCO190-775T , 200kH z chan-

nel spacing and 20kHz loop band-width.

Figure 1. Evaluation Board Silkscreen

T he board is powered from a single 9V battery. T he

power supply ciruitry allows the user to choose either 3V

or 5V for the ADF4213 V_DDand V_P, and for the VCO

supply. T he default settings are 3V for the ADF4213 V_DD

and 5V for the ADF4213 V_Pand for the VCO supply. It

is ver y im por tant to note that the AD F4213 V_{D D}should

never exceed the AD F4213 V_P. This can dam age the de-

vice.

All components necessary for LO generation are on-

board. T he 19.2 MHz T CXO from Vectron provides the

necessary Reference Input. T he PLL on the RF side is

made up of the ADF4213, passive loop filter (20kHz

bandwidth) and the VCO 190-2350 from Vari-L. T he

PLL on the IF consistes of the ADF4213, passive loop

filter (20kHz bandwidth) and the VCO 190-775. T he

respective outputs are available at RFOUT and IFOUT

through standard SMA connectors. If the user wishes they

may use their own power supplies and reference input. In

this case, they need to insert SMA connectors to as shown

on the silkscreen and block diagram.

T he AD7706 A/D converter is used to monitor the power

supply voltage and current consumption of the ADF4213.
