Technical Context

The ADPA7009-2-EVALZ implements a balanced 4-stage cascaded amplifier architecture using two 90° hybrids, enabling 17.5 dB gain and 28.5 dBm PSAT at 20–35 GHz. Its PCB layout integrates 50 Ω microstrip routing, ground-via arrays under the CE-24-2 LGA_CAV package, and dedicated test points for RFIN, RFOUT, VDD1/VDD2 (5 V), VGG1/VGG2 (−1.5 V to 0 V), VDET, and VREF.

It supports both north-side (VGG1/VDD1) and south-side (VGG2/VDD2) bias configurations, includes on-board 0.1 μF and 100 pF decoupling capacitors per supply rail, and provides temperature-compensated RF output power monitoring via the differential VREF − VDET interface referenced to the ADPA7009-2's internal detector diodes.

FAQ

What is the primary function of the ADPA7009-2-EVALZ?

The ADPA7009-2-EVALZ is an evaluation board designed exclusively for the ADPA7009-2 GaAs pHEMT MMIC power amplifier. It provides a fully assembled, tested PCB with SMA RF interfaces, accessible bias and detector terminals, integrated decoupling, and thermal grounding to enable immediate RF performance validation, gain flatness measurement, and temperature-compensated power detection across 20–54 GHz. The ADPA7009-2-EVALZ does not contain active circuitry beyond what is required to host and interface the ADPA7009-2 die.

Does the ADPA7009-2-EVALZ include the ADPA7009-2 IC?

Yes, the ADPA7009-2-EVALZ ships with the ADPA7009-2 GaAs pHEMT MMIC amplifier pre-mounted in its 24-terminal CE-24-2 LGA_CAV package. The board is factory-assembled and tested, with the ADPA7009-2 IC soldered to the PCB and all matching networks, bias lines, and detector interfaces completed per Analog Devices' reference layout guidelines.

How is bias sequencing implemented on the ADPA7009-2-EVALZ?

The ADPA7009-2-EVALZ supports manual and automated bias sequencing. For manual operation, users apply −1.5 V to VGG1 before enabling 5 V on VDD1, then adjust VGG1 upward to achieve 850 mA IDQ. For automated control, the board includes a footprint and routing for the HMC980LP4E active bias controller, which enforces safe gate-first power-up and closed-loop drain current regulation. All sequencing requirements for the ADPA7009-2-EVALZ are defined in the official ADPA7009-2-EVALZ user guide.

Can the ADPA7009-2-EVALZ be used for detector calibration?

Yes, the ADPA7009-2-EVALZ provides direct access to the VDET and VREF pins of the ADPA7009-2 IC, enabling precise measurement of the temperature-compensated detector output (VREF − VDET). This differential voltage is proportional to RF output power and can be calibrated against known input tones and power levels across 20–54 GHz. The board maintains the 50 Ω environment and thermal grounding needed for repeatable detector characterization as specified in the ADPA7009-2 datasheet Figures 47–50.

What documentation accompanies the ADPA7009-2-EVALZ?

The ADPA7009-2-EVALZ is supported by the official ADPA7009-2-EVALZ User Guide (UG-1922), which details PCB layout, component placement, test setup, biasing procedures, detector interface schematics, and measurement best practices. It references the ADPA7009-2 datasheet (Rev. 0) for device-level specifications and must be used in conjunction with the HMC980LP4E datasheet when implementing active bias control. No separate schematic or bill-of-materials is shipped with the board - all are published online by Analog Devices.
