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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
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.
