EVALUATION BOARD

To operate correctly under Windows XP, Version 3.5 of

Microsoft .NET must be installed. To run the software on a

Windows 7 PC, XP emulation mode must be used (using

Virtual PC).

Figure 52 shows the schematic of the device’s RoHS-compliant

evaluation board. This board was designed using Rogers 4350

material to minimize losses at high frequencies. FR4 material

would also be adequate but with the slightly higher trace loss

of this material.

Whereas the on-board USB interface circuitry of the evaluation

board is powered directly from the PC, the main section of the

evaluation board requires a separate 5 V power supply.

The evaluation board is designed to operate using the internal

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

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

removed. 0 Ω resistors should be placed in R63 and R11. A

side-launched SMA connector (Johnson 142-0701-851) must

be soldered to the pad labeled VTUNE. The input of the

external VCO should be connected to the VTUNE SMA

connector and a portion of the VCO’s output should be

connected to the EXT LO SMA connector. In addition to

these hardware changes, internal register settings must also

be changed (as detailed in the Register Description section)

to enable operation with an external VCO.

Additional configuration options for the evaluation board are

described in Table 11.

Figure 51. Control Software Opening Menu

The serial port of the ADRF6701 can be programmed from a

PC’s USB port (a USB cable is provided with the evaluation

board). The on-board USB interface circuitry can if desired be

bypassed by removing the 0 Ω resistors, R15, R17, and R18 (see

Figure 52) and driving the ADRF6701 serial interface through

the P3 4-pin header (P3 must be first installed, Samtec TSW-

104-08-G-S).

Figure 51 shows the opening window of the software where the

user selects the device being programmed. Figure 55 shows a

screen shot of the control software’s main controls with the

default settings displayed. The text box in the bottom left corner

provides an immediate indication of whether the software is

successfully communicating with the evaluation board. If the

evaluation board is connected to the PC via the USB cable

provided and the software is successfully communicating with

the on-board USB circuitry, this text box shows the following

message: ADRF6X0X eval board connected.

EVALUATION BOARD CONTROL SOFTWARE

USB-based programming software is available to download

from the ADRF6701 product page at www.analog.com

(Evaluation Board Software Rev 6.1.0). To install the software,

download and extract the zip file. Then run the following

installation file: ADRF6X0X_6p1p0_customer_installer.exe.
