GENERAL DESCRIPTION
The ADL9005-EVA LZ consists of a 2-layer printed circuit board
(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 ADL9005-EVA L Z are
populated with 2.9 mm, female coaxial connectors, and the
respective RF traces have a 50 Ω characteristic impedance. The
ADL9005-E VA L Z is populated with components suitable for use
over the entire −40°C to +85°C operating temperature range of
the ADL9005.
To calibrate out board trace losses, a through calibration path,
THRU CAL, is provided between the RFINTHRU and THRUCAL
connectors. RFINTHRU and 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 to
provide bias current and ac coupling on RFOUT. The BT2-0040
from Marki Microwave is recommended.
Alternatively, dc bias can be provided by connecting the dc
supply voltage to the VDDOPT SMT test point.

The RF traces are 50 Ω, grounded, coplanar waveguide. The
package ground leads and the exposed pad directly connect to
the ground plane. Multiple vias are used to 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 to the heat spreader.

which must be consulted in conjunction with this user guide
when using the ADL9005-EVA L Z .

EVALUATION BOARD HARDWARE
PROVIDING DC BIAS THROUGH A CONNECTORIZED
BIAS TEE
A 5 V, 200 mA supply is required to provide the bias to the
ADL9005 when using the ADL9005-EVA LZ. Connect the 5 V
supply through an external bias tee, such as the Marki Microwave
BT2-0040, to the RFOUT port (see Figure 3). Connect the same
5 V supply to the VBIAS SMT test point. A connectorized dc
blocking capacitor must be connected to the RFIN port because
there is not an ac coupling capacitor on the RF input trace on
the ADL9005-EVA LZ. The R1 value (default value is 300 Ω)
sets the total current (IDQ) to 80 mA.

Recommended Bias Sequencing
To avoid damaging the device, careful attention must be paid to
the sequencing of the RF input, the bias voltage, and the drain
bias voltage. The following power-up sequencing is recommended:
1. Connect GND.
2. Increase the voltage on the VBIAS SMT test point and the
external bias tee t o 5 V.
3. Apply the RF signal.
The following power-down sequencing is recommended:
1. Turn off the RF signal.
2. Reduce the voltage on the VBIAS SMT test point and
the external bias tee to 0 V.
PROVIDING DC BIAS THROUGH THE ACG4/VDD2 PIN
An alternative way to bias the ADL9005 when using the ADL9005-
EVA LZ is by applying 8.5 V to the ACG4/VDD2 pin through the
VDDOPT SMT test point and by applying 5 V to the RBIAS pin
through the VBIAS SMT test point.
The VDDOPT SMT test point connects directly to the ACG4/
VDD2 pin on the ADL9005. The higher 8.5 V supply is required
to make up for the voltage drop across an internal resistor so
that the internal drain bias voltage is still equal to 5 V.
Applying this 8.5 V supply voltage to the VDDOPT SMT test
point removes the need for an external bias tee, which must be
replaced with a connectorized dc block on the RFOUT port
(see Figure 4).
With 5 V applied to the VBIAS SMT test point and the default
value of R1 at 300 Ω, the resulting IDQ is 80 mA. The VBIAS
SMT test point can also be connected directly to the 8.5 V
supply. However, to do this, the R1 value must be increased
to 850 Ω to maintain an IDQ of 80 mA.

Recommended Bias Sequencing when Providing Bias
Through the VDDOPT SMT Test Point
The following sequencing is recommended for power-up when
providing bias through the VDDOPT SMT test point:
1. Connect GND.
2. Increase the voltage on the VDDOPT SMT test point to 8.5 V.
3. Increase the voltage on the VBIAS SMT test point to 5 V.
4. Apply the RF signal.
The following sequencing is recommended for power-down
when providing bias through the VDDOPT SMT test point:
1. Remove the RF signal.
2. Decrease the voltage on the VBIAS SMT test point to 0 V.
3. Decrease the voltage on the VDDOPT SMT test point to 0 V.

THROUGH CALIBRATION PATH
The ADL9005-EVA LZ includes a calibration path (see the
evaluation board schematic in Figure 6). RFINTHRU and
THRUCAL must be populated with RF connectors to use the
through calibration path. Figure 5 shows the insertion loss, input
return loss and output return loss of the through calibration path.
