EVAL-ADL8100

Product Details

The ADL8100ACPZN-EVALZ and ADL8100ACPZN-EVAL1Z are 2-layer printed circuit boards (PCB) fabricated from 10 mil thick, Rogers 4350B, copper clad, mounted to an aluminum heat spreader. The heat spreader assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat spreader allow attachment to larger heat sinks for improved thermal management.

The RFIN and RFOUT ports on the ADL8100ACPZN-EVALZ and ADL8100ACPZN-EVAL1Z are populated with 2.9 mm, female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADL8100ACPZN-EVALZ and ADL8100ACPZN-EVAL1Z are populated with components suitable for use over the entire −40°C to +85°C operating temperature range.

To calibrate out board trace losses, a through calibration path, THRUCAL, is provided between the THRUCAL connectors (J1 and J2). THRUCAL must be populated with RF connectors to use the through calibration path.

The power voltages and ground path are accessed through surface- mounted technology (SMT) test points.

An external wideband bias tee must be connected to RFOUT of the ADL8100ACPZN-EVALZ to provide bias current and AC coupling on RFOUT. The BT2-0040 from Marki Microwave is recommended. The ADL8100ACPZN-EVAL1Z has an on-board SMT bias tee.

For full details on the ADL8100, see the ADL8100 data sheet, which must be consulted in conjunction with the user guide when using the ADL8100ACPZN-EVALZ and ADL8100ACPZN-EVAL1Z.
