20 MH TO 500 MH IF Gain Block

The ADL5531 is a broadband, fixed-gain, linear amplifier that operates at frequencies up to 500 MHz. The device can be used in a wide variety of equipment, including cellular, satellite, broadband, and instrumentation equipment.

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.
