EVALUATION BOARD

Figure 50 shows the schematic of the RoHS-compliant evaluation

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 hardware changes, internal

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 under the Evaluation Boards

& Kits section. To install the software

1. Download and extract the zip file:

ADRF6x0x_customer_6p0p0_install.zip file.

2. Follow the instructions in the read me 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 48). 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

(EVAL-ADF4XXXZ-USB) must be purchased from Analog Devices.

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.
