Product DetailsThe ADL5523 is a high performance GaAs pHEMT low noise amplifier. It provides high gain and low noise figure for single-downconversion IF sampling receiver architectures as well as direct-downconversion receivers.
The ADL5523 provides a high level of integration by incorporating the active bias and the dc blocking capacitors, making it very easy to use while not sacrificing design flexibility.
The ADL5523 is easy to tune, requiring only a few external components. The device can support operation from 3 V to 5 V, and the current draw can be adjusted with the external bias resistor for applications requiring very low power consumption.
The ADL5523 comes in a compact, thermally enhanced, 3 mm × 3 mm LFCSP and operates over the temperature range of −40°C to +85°C.
A fully populated evaluation board is also available.

Evaluation Kits (2)
ADL5523-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation it requires a single 5 V/100 mA power supply. The 5 V power supply should be connected to the test loops labeled VPOS and GND. Alternatively, the power supply connections may be made via the two pin header, W-1. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT.
The Quad-MxFE System Development Platform contains four MxFE® software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking, and power circuitry. The target application is phased array radars, electronic warfare, and ground-based SATCOM, specifically a 16 transmit/16 receive channel direct sampling phased array at L/S/C band (0.1 GHz to ~5GHz). The Rx & Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.
The Quad-MxFE System Development Platform highlights a complete system solution. It is intended as a testbed for demonstrating multi-chip synchronization as well as the implementation of system level calibrations, beamforming algorithms, and other signal processing algorithms. The system is designed to mate with a VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+™ XCVU9P FPGA, with provided reference software, HDL code, and MATLAB system-level interfacing.
In addition to the Quad-MxFE Digitizing Card, the kit also contains a 16Tx / 16Rx Calibration Board that is used to develop system-level calibration algorithms, or otherwise more easily demonstrate power-up phase determinism in situations pertinent to their own use case. The Calibration Board also allows the user to demonstrate combined-channel dynamic range, spurious, and phase noise improvements and can also be controlled via a free MATLAB add-on when connected to the PMOD interface of the VCU118.
The system can be used to enable quick time-to-market development programs for applications like:
- ADEF (Phased-Array, RADAR, EW, SATCOM)
- Communications Infrastructure (Multiband 5G and mmWave 5G)
- Electronic Test and Measurement
