Product Usage Instructions

Operating the ADAR5001-EVALZ

A 2-port network analyzer is required to evaluate the ADAR5001-EVALZ. The through, open, and short lines can be used to de-embed the board trace losses, but these lines must be first populated with RF connectors.

Insertion Loss and Return Loss

Table 1 provides the insertion loss values for the through calibration path at different frequencies. Figure 3 illustrates the return loss and insertion loss for the through calibration path from 10 GHz to 40 GHz.

Evaluation Board Schematic and Artwork

Refer to the schematic (Figure 4) and assembly drawing (Figure 5) for detailed information on the board layout and components.

FAQ

Q: What equipment is needed to evaluate the ADAR5001-EVALZ?

GENERAL DESCRIPTION

ADAR5001-EVALZ is a copper clad, 4-layer printed circuit board (PCB) fabricated from 0.254 mm (10 mil) thick, Rogers 4350B. The central core is prepreg, and there is an unused FR4 layer on the underside, which forms a nominal thickness of 1.574 mm (62 mils). The P1, P2, and SUM ports on the ADAR5001-EVALZ are populated with 2.92 mm, female coaxial connectors, and the corresponding microstrip RF traces have a 50 Ω characteristic impedance. To calibrate board trace losses, a through calibration path is provided between the J6 and J7 connectors. Open and short paths are provided on the J5 and J4 connectors. Connectors J4, J5, J6 and J7 are de-populated and must be added to use the calibration traces. Refer to Table 1 and Figure 3 for the through calibration path performance.
For full details on the ADAR5001, see the ADAR5001 data sheet, which must be consulted in conjunction with this user guide when using the ADAR5001-EVALZ.
