20 MHz TO 500 MHz IF Gain Block
The ADL5531 provides a gain of 20 dB, which is stable over frequency, temperature, power supply, and from device to device. This amplifier is single-ended and internally matched to 50 Ω. Only input/output ac coupling capacitors, power supply decoupling capacitors, and external inductors are required for operation.
The ADL5531 is fabricated on a GaAs HBT process and has an ESD rating of ±2 kV (Class 2). The device is packaged in an 8-lead 3 mm × 3 mm LFCSP that uses an exposed paddle for excellent thermal impedance.
The ADL5531 consumes 100 mA on a single 5 V supply and is fully specified for operation from −40°C to +85°C.
The dual-channel 20 dB gain version, ADL5534, is also available.

ADL5531-EVALZ is a 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.
