20 MH TO 500 MH IF Amplifier

The ADL5534 contains two broadband, fixed-gain, linear amplifiers and 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 ADL5534 has a fixed gain of 20 dB, which is stable over frequency, temperature, power supply, and from device-to-device. The amplifiers are single-ended and internally matched to 50 Ω. Only input/output ac-coupling capacitors, power supply decoupling capacitors, and an external bias inductor are required for operation of each amplifier

The ADL5534 is fabricated on a GaAs HBT process. The device is packaged in a 16-lead 5 mm × 5 mm LFCSP that uses an exposed paddle for excellent thermal impedance. The ADL5534 consumes 98 mA of current per amplifier on a single 5 V supply, and is fully specified for operation from −40°C to +85°C. A similar amplifier, ADL5531 (available from Analog Devices, Inc.) is the 20 dB gain single-channel version. Fully populated evaluation boards for both the ADL5531 and ADL5534 are available.
