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 characteristic impedance. The ADL8150-EVALZ is populated with components suitable for use over the entire -40C to +85C 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. 25524-001 GENERAL DESCRIPTION Figure 1. ADL8150-EVALZ Primary Side The RFIN and RFOUT traces on the ADL8150-EVALZ are 50 , 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 ADL8150EVALZ 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 this user guide when using the ADL8150-EVALZ. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS.

By default, the ADL8150-EVALZ is configured to use the regulator to power the ADL8150. The regulator is configured to provide 5 V to the ADL8150. To adjust the output voltage (VOUT), change the R3 resistor value (see Table 1). When using the regulator, connect a 5.5 V, 200 mA power supply between the surface-mount technology (SMT) pins, VIN and GND. Table 1. R3 Resistor Values vs. Regulator VOUT R3 (k) 45 49.9 55 VOUT (V) 4.5 5 5.5 The recommended bias sequence during power-up follows: Connect a 5.5 V, 200 mA power supply to the SMT test point, VIN. Connect the ground reference to the GND test point. Apply RF. POWER DOWN The recommended bias sequence during power-down follows: 1. 2. Turn off the RF.
