Подробнее о продукте

The ADL8150-EVALZ consists of a 4-layer printed circuit board (PCB) fabricated from 10 mil thick, Rogers 4350B and Isola 370HR, copper clad, forming a nominal thickness of 62 mils. The RFIN and RFOUT ports on the ADL8150-EVALZ are populated with 2.9 mm, female coaxial connectors, and the corresponding RFIN and RFOUT traces have a 50 Ω characteristic impedance. The ADL8150-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL8150. 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 2 and Figure 3 for the through calibration path performance.

Incorporated on the ADL8150-EVALZ is an ultralow noise, ultrahigh power supply rejection ratio (PSRR), linear regulator. This low noise regulator provides a clean power source to bias the ADL8150.

The RFIN and RFOUT traces on the ADL8150-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 pad to provide adequate electrical conduction and thermal conduction.

The power supply decoupling capacitors on the ADL8150-EVALZ represent the configuration used to characterize and qualify the device. For full details on the ADL8150, see the ADL8150 data sheet, which must be consulted in conjunction with the user guide when using the ADL8150-EVALZ.
