GENERAL DESCRIPTION
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.
