GENERAL DESCRIPTION

The ADL8142-EVALZ consists of a 4-layer printed circuit board

(PCB) fabricated from 8 mil thick, Rogers 4003C and Isola 370HR,

copper clad, forming a nominal thickness of 62 mils. The RFIN and

RFOUT ports on the ADL8142-EVALZ are populated with

2.92 mm, female coaxial connectors, and the corresponding RF

traces have a 50 Ω characteristic impedance. The ADL8142-EVALZ

is populated with components suitable for use over the entire −40°C

to +85°C operating temperature range of the ADL8142. To calibrate

board trace losses, a through calibration path is provided between

the J1 and J2 connectors. J1 and J2 must be populated with RF

connectors to use the through calibration path. Refer to Table 1 and

Figure 3 for the through calibration path performance.

Access the ADL8142-EVALZ ground path and VDD pin through the

surface-mount technology (SMT) test point connectors, GND and

VDD. A supplementary test point for VBIAS is included for simple

access on the RBIAS pin (see Figure 5 for the test point assembly).

The RF traces on the ADL8142-EVALZ are 50 Ω, grounded, coplanar

waveguide. The package ground leads and the exposed pad

connect directly to the ground plane. Multiple vias connect the

top and bottom ground planes with particular focus on the area

directly beneath the ground paddle to provide adequate electrical

conduction and thermal conduction to the heat sink.

The power supply decoupling capacitors on the ADL8142-EVALZ

represent the configuration used to characterize and qualify the

device.

For full details on the ADL8142, see the ADL8142 data sheet,

which must be consulted in conjunction with this user guide when

using the ADL8142-EVALZ.
