Evaluation Board Hardware

Overview

The ADRF5301-EVALZ is a connectorized evaluation board assembled
with the ADRF5301 device and application circuitry. All components
are located on the primary side of the ADRF5301-EVALZ.

Board Layout

The ADRF5301-EVALZ is designed using RF circuit design
techniques on a 4-layer printed circuit board (PCB). The PCB
stack-up is shown in Figure 2 (not provided).

RF Inputs and Outputs

The RF input and output ports (RFC, RF1, and RF2) are connected
through 50Ω transmission lines to the 2.4 mm RF connectors, as
shown in Table 1. These high-frequency RF connectors are installed
onto the ADRF5301-EVALZ by contact and are not soldered onto the
board.

A through line (THRUCAL) is provided for calibration and
connects the unpopulated RF connectors. This transmission line is
the trace loss from the ADRF5301-EVALZ and is used to determine the
device performance at the pins of the IC.

EVALUATION BOARD HARDWARE
OVERVIEW
The ADRF5301-EVALZ is a connectorized evaluation board assembled with the ADRF5301 device and application circuitry. All components are located on the primary side of the ADRF5301-EVALZ. Figure 5 shows the ADRF5301-EVALZ schematic, and Figure 6 shows the assembly drawing. Table 4 shows the bill of materials for the ADRF5301-EVALZ components.
BOARD LAYOUT
The ADRF5301-EVALZ is designed using RF circuit design techniques on a 4-layer printed circuit board (PCB). The PCB stack-up is shown in Figure 2.

RF INPUTS AND OUTPUTS

The RF input and output ports (RFC, RF1, and RF2) are connected through 50 transmission lines to the 2.4 mm RF connectors, as shown in Table 1. These high-frequency RF connectors are installed onto the ADRF5301-EVALZ by contact and are not soldered onto the board.

Through Line Input and Output

A through line (THRUCAL) is provided for calibration and connects the unpopulated RF connectors. This transmission line is the trace loss from the ADRF5301-EVALZ and is used to determine the device performance at the pins of the IC.

Figure 2. Evaluation Board Stack-Up
The outer copper layers are 1.5 oz (2.2 mil) thick and the inner layers are 0.5 oz (0.7 mil) thick.
All RF and DC traces are routed on the top copper layer, whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. The top dielectric material is 8 mil Rogers RO4003, offering optimal high-frequency performance. The middle and bottom dielectric materials provide mechanical strength. The total board thickness is 62 mil, which allows 2.4 mm RF edge launch connectors to be placed at the board edges.
The RF transmission lines are designed using a coplanar waveguide (CPWG) model with a width of 14 mil and ground spacing of 7 mil to have a characteristic impedance of 50 . Ground via fences is arranged on both sides of a coplanar waveguide to improve isolation between nearby RF lines and other signal lines.

POWER SUPPLY AND CONTROL INPUTS

Because the ADRF5301 incorporates a negative voltage generator (NVG) to operate with a single positive supply of 3.3 V applied to the VDD pin, only one power supply is needed to power up the ADRF5301-EVALZ. The control input is connected to the CTRL test point, and the ground reference is connected to the GND test point.

On the supply trace, a 100 pF bypass capacitor filters the high-frequency noise. Additionally, unpopulated component positions are available for applying extra bypass capacitors.

On the control trace, there are provisions for an RC filter to eliminate DC- coupled noise, if required by the application.

TEST PROCEDURE
The ADRF5301-EVALZ is shipped assembled and tested. Figure 4 shows a basic setup diagram to measure the scattering parameter response of the ADRF5301. To complete the test setup and verify the operation of the ADRF5301-EVALZ, perform the following steps:
1. Connect the GND test point to the ground terminal of the two 3.3 V DC power supplies.
2. Connect the VDD test point to the voltage-output terminal of the 3.3 V DC power supply.
3. Connect the CTRL test point to the voltage-output terminal or ground terminal of the other 3.3 V DC power supply. The

EVAL-ADRF5301
ADRF5301 can be configured in different modes by connecting the CTRL test point to 3.3 V or 0 V, as shown in Table 3. 4. Connect the RFC, RF1, and RF2 ports to a calibrated network analyzer. 5. Turn on the 3.3 V DC power supply connected to the VDD test point. 6. Turn on the 3.3 V DC power supply connected to the CTRL test point. 7. Measure the scattering parameters.
