GENERAL DESCRIPTION
The ADL5534 contains two broadband, fixed-gain, linear The ADL5534 is fabricated on a GaAs HBT process. The amplifiers and operates at frequencies up to 500 MHz. The device is packaged in a 16-lead 5 mm × 5 mm LFCSP that device can be used in a wide variety of equipment, including uses an exposed paddle for excellent thermal impedance. cellular, satellite, broadband, and instrumentation equipment. The ADL5534 consumes 98 mA of current per amplifier on The ADL5534 has a fixed gain of 20 dB, which is stable over a single 5 V supply, and is fully specified for operation from frequency, temperature, power supply, and from device-to- −40°C to +85°C. device. The amplifiers are single-ended and internally matched A similar amplifier, ADL5531 (available from Analog Devices, to 50 Ω. Only input/output ac-coupling capacitors, power supply Inc.) is the 20 dB gain single-channel version. Fully populated decoupling capacitors, and an external bias inductor are evaluation boards for both the ADL5531 and ADL5534 are required for operation of each amplifier. available.
