EVALUATION BOARD

Figure 24 shows the schematic of the RoHS-compliant evalua-

tion board for the ADRF6603. This board has four layers and

was designed using Rogers 4350 hybrid material to minimize

high frequency losses. FR4 material is also adequate if the design

can accept the slightly higher trace loss of this material.

The evaluation board is designed to operate using the internal

VCO of the device (the default configuration) or with an

external VCO. To use an external VCO, R62 and R12 should

be removed. Place 0 Ω resistors in R63 and R11. The input of

the external VCO should be connected to the VTUNE SMA

connector, and the external VCO output should be connected

to the LO IN/OUT SMA connector. In addition to these hard-

ware changes, internal register settings must also be changed to

enable operation with an external VCO (see the Register 6—

VCO Control and VCO Enable (Default: 0x1E2106) section).

Additional configuration options for the evaluation board are

described in Table 10.

EVALUATION BOARD CONTROL SOFTWARE

Software to program the ADRF6603 is available for download

from www.analog.com. To install the software, download and

extract the zip file. Then run the following installation file:

ADRF6x0x_3p0p0_XP_install.exe

The evaluation board can be connected to the PC using a PC

parallel port or a USB port. These options are selectable from

the opening menu of the software interface (see Figure 22). The

evaluation board is shipped with a 25-pin parallel port cable

for connection to the PC parallel port.

To connect the evaluation board to a USB port, a USB adapter

board (Part No. EVAL-ADF4XXXZ-USB) must be purchased

from www.analog.com. This board connects to the PC using a

standard USB cable with USB mini-connector at one end. An

additional 25-pin male to 9-pin female adapter is required to

mate the ADF4XXXZ-USB board to the 9-pin D-Sub connector

on the ADRF6603 evaluation board.
