GENERAL DESCRIPTION
The ADL5545 is a single-ended RF/IF gain block amplifier
that provides broadband operation from 30 MHz to 6 GHz.
The ADL5545 provides over 36 dBm of OIP3 using only 56 mA
from a 5 V supply.
The ADL5545 is fabricated on an InGaP HBT process and has
a high ESD rating of 1.5 kV (Class 1C). The ADL5545 is also
fully specified for operation across the wide temperature range of
−40°C to +105°C. A fully populated RoHS-compliant evaluation
board is available.
The ADL5545 provides a gain of 24 dB, which is stable over
frequency, temperature, power supply, and from device to device.
The amplifier is offered in the industry-standard SOT-89 package
and is internally matched to 50 Ω at the input and output, making
the ADL5545 very easy to implement in a wide variety of applica-
tions. The only external components required are the input/output
ac coupling capacitors, power supply decoupling capacitors, and
dc bias inductor.
