ADRF6604
EVALUATION BOARD
Figure 24 shows the schematic of the RoHS-compliant evalu-
ation board for the ADRF6604. 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 using 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 ADRF6604 is available for download
from the ADRF6604 product page at www.analog.com. To install
the software, download and extract the zip file. Then run the
ADRF6x0x_3p0p0_XP_install.exe installation file.
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 a USB mini-connector at one end. An
additional 25-pin male to 9-pin female adapter is required to
mate the EVAL-ADF4XXXZ-USB board to the 9-pin D-Sub
connector on the ADRF6604 evaluation board.
Figure 23 shows the main window of the control software with
the default settings displayed.
