EVALUATION BOARD HARDWARE The ADRF6820 evaluation board provides all of the support circuitry required to operate the ADRF6820 in its various modes and configurations. Figure 2 shows the typical bench setup used to evaluate the performance of the ADRF6820.

POWER SUPPLY The ADRF6820 evaluation board requires a quiet 6 V power source. This 6 V power source feeds the power supply design on the ADRF6820 evaluation board that consists of switches and dc regulators. Via the switches and/or dc regulators, 3.3 V and 5.0 V power rails are provided to the main IC.

RF INPUTS The high isolation 2:1 RF switch and on-chip tunable RF balun enable the ADRF6820 to support two single-ended, 50 Ω termi-nated RF inputs. The 2:1 RF switch can be controlled serially via the SPI port or in parallel via Switch S1. The default configuration is parallel control using the switch. The operational frequency range of the RF inputs is from 695 MHz to 2700 MHz; these inputs should be ac-coupled.

LO INPUT/OUTPUT The ADRF6820 offers two alternatives for generating the differential local oscillator (LO) input signal:

• Generate the signal externally via a high frequency, low phase noise LO signal.

• Generate the signal internally via the on-chip Fractional-N synthesizer.

In either case, the differential LO signal can be routed off chip to SMA connectors labeled LOOP and LOON for the purpose of daisy-chaining multiple ICs requiring LO signals.

For an internal LO configuration using the on-chip Fractional-N synthesizer, apply a low phase noise reference signal to the REF_IN connector. The PLL reference input can support a wide frequency range because the divide or multiplication block can be used to increase or decrease the reference frequency to the desired value before the signal is passed to the phase frequency detector (PFD). The integrated synthesizer enables continuous LO coverage from 356.25 MHz to 2850 MHz.

For optimum performance using an external LO source, the LO input pins (LOIN− and LOIN+) should be driven differentially. The wide input range of the external LO inputs span from 350 MHz to 6000 MHz. Unless an ac-coupled balun/transformer is used to generate the differential LO, the inputs must be ac-coupled. The input impedance of the differential LO signals is 50 Ω.

QUADRATURE I/Q OUTPUTS On the evaluation board, the quadrature I/Q outputs are ter-minated with 200 Ω differential. This is achieved by using a 1:1 transformer and an L-impedance matching network. The 1:1 transformer, TC1-1-13M+ from Mini-Circuits, is a very wide bandwidth (4.5 MHz to 3000 MHz) transformer that allows a flat pass-band response of up to 1 GHz. Using a wide bandwidth transformer is necessary to accurately evaluate the wideband pass-band response of the ADRF6820 without the effects of the

transformer/balun roll-off. However, to terminate the ADRF6820 with 200 Ω and also match the output impedance of the transformer with 50 Ω, an L network is placed between the I/Q outputs and the transformer. This introduces some power loss because the L network acts as a voltage divider (see Figure 3). The power loss due to the L network is approximately 17 dB.

Figure 3. I/Q Output Matching Network

To avoid the power loss from the L network while achieving the proper impedance matching, a 4:1 impedance transformer, such as the TC4-1W+ from Mini-Circuits can be used in place of the TC1-1-13M+. This 4:1 impedance transformer allows the primary side of the transformer to be terminated with 200 Ω and the secondary side to be terminated with 50 Ω. The L network then becomes unnecessary and can be shorted out by replacing R35, R36, R37, and R38 with 0 Ω while R31, R32, R33, R34, R39, R40, R41, and R42 can all be DNI (do not install). Attention needs to be paid to the bandwidth of the transformer because impedance transformation transformers tend to have narrower bandwidths. The TC4-1W+ has a listed bandwidth of 3 MHz to 800 MHz; however, the 1 dB bandwidth is limited to 100 MHz. As a result, the roll-off of the transformer may distort the pass-band flatness of the ADRF6820, depending on which bandwidth configuration is used for the ADRF6820.

EVALUATION BOARD CONTROL SOFTWARE The ADRF6820 evaluation board is configured with a USB friendly interface to allow programmability of the ADRF6820 registers.

SOFTWARE INSTALLATION PROCEDURES The following instructions describe how to install the ADRF6820 control software, as well as the Cypress generic USB driver, on a computer running a Windows XP, Windows Vista, or Windows 7 (32- or 64-bit) operating system.

Warning

Install the necessary software before plugging the USB cable into the computer.

Installing the Evaluation Software

1. From the extracted folder, ADI_RFG_Drivers, double-click the ADI_RFG_Drivers.exe file. Running this file allows the installation of the Cypress CyUSB.sys driver as a verified, signed driver.

2. From the extracted .zip file, double-click the ADRF6820_ install.exe file. An icon should appear on your desktop with the ADI logo, titled ADRF6820.

3. After the installer is finished, install the USB driver.

Installing the Driver

1. Connect the USB connector on the evaluation board to the PC using the USB cable that was included in the box.

2. In either Windows XP or Windows Vista, right-click My Computer and then select Properties.

3. Open the Device Manager. a. In Windows Vista or Windows 7, select the Device

Manager option. b. In Windows XP, select the Hardware tab and then

click Device Manager. 4. In Device Manager, select the last category, Universal

Serial Bus Controllers. You should see an entry that either

has a yellow flag (indicating an unknown device) or an entry labeled ADF4xxx USB Driver (if you have installed a previous ADRF6x0x or ADI Limerick PLL software).

5. Right-click on the appropriate device and select update driver. 6. Browse to select the directory C:\Program Files\

ADRF6820_customer_software. 7. Click Next. Windows completes the driver installation.

USING THE ADRF6820 EVALUATION SOFTWARE ADRF6820 Tab

The main window of the ADRF6820 evaluation software includes a block diagram that shows how the registers affect the major functional blocks of the ADRF6820 (see Figure 4). Within this window, the green boxes indicate that user input is required, and the yellow boxes indicate read only information.

To use the ADRF6820 evaluation software,

1. Before reading or writing to the registers, validate the USB connection by reading the USB indicators located in the lower left corner of the main window.

2. Click Update GUI to read the register values from the device and update the user interface. (An automatic write to the chip is initiated every time a register value is changed from the user interface.)

3. Specify the PLL reference and the desired LO frequency by typing the appropriate values into the designated boxes. Press ENTER after each input, and the software (via the PLL synthesizer blocks) calculates and sets the INT, FRAC, and MOD values accordingly.

Engineering Tab

The Engineering tab (see Figure 5) allows specific reads and writes to individual registers. Be sure to type values into the Address (decimal) and Write Data (decimal) boxes in decimal format.
