Product Details

The ADL8140-EVALZ is 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 ADL8140-EVALZ are populated with female coaxial 2.9 mm connectors, and the corresponding RF traces have a 50 Ω characteristic impedance. The ADL8140-EVALZ is populated with components suitable for use over the entire −55°C to +125°C operating temperature range of the ADL8140. To calibrate board trace losses, a through calibration path is provided between the J1 and J2 connectors. J1 and J2 must be populated with 2.9 mm RF connectors to use the through calibration path. Refer to Table 1 and Figure 3 for the through calibration path performance.

Connect ground and power to ADL8140-EVALZ using the surfacemount 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 6 for the test point assembly).

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.

The power supply decoupling capacitors on the ADL8140-EVALZ represent the configuration used to characterize and qualify the device.

For full details on the ADL8140, see the ADL8140 data sheet, which must be consulted in conjunction with this user guide when using the ADL8140-EVALZ evaluation board.
