The ADL8130-EVALZ is a 4-layer printed circuit board (PCB) fabricated
from 0.254mm (10mil) thick, Rogers 4003C, copper clad,
forming a nominal thickness of 1.58mm (62mils). The ADL8130-
EVALZ is designed to operate from 0.01GHz to 8GHz. The RFIN
and RFOUT ports on the ADL8130-EVALZ are populated with
2.9mm, female coaxial connectors. The ADL8130-EVALZ is populated
with components suitable for use over the entire −55°C to
+125°C operating temperature range.
To calibrate out 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 Figure 5 and Table 1 in user guide for the through calibration path
performance for the ADL8130-EVALZ.
Access the ADL8130-EVALZ ground and drain voltage through the
surface-mount technology (SMT) test point connectors, GND and
VDD. A supplementary test point for VRBIAS is included for simple
access on the RBIAS pin (see Figure 6 and Figure 7 in user guide for the test
point locations).
The RF traces on the ADL8130-EVALZ are 50Ω, 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.
The power supply decoupling capacitors on the ADL8130-EVALZ
represent the configuration used to characterize and qualify the
device.
For full details on the ADL8130, see the ADL8130 data sheet,
which must be consulted in conjunction with this user guide when
using the ADL8130-EVALZ.
