GENERAL DESCRIPTION
The ADL5541 is a broadband 15 dB linear amplifier that operates
at frequencies up to 6 GHz. The device can be used in a wide
variety of CATV, cellular, and instrumentation equipment.
The ADL5541 provides a gain of 15 dB, which is stable over
frequency, temperature, power supply, and from device to
device. The device is internally matched to 50 Ω with an input
return loss of 10 dB or better up to 6 GHz. Only input/output
ac coupling capacitors, power supply decoupling capacitors, and
an external inductor are required for operation.
The ADL5541 is fabricated on an InGaP HBT process and has
an ESD rating of 1 kV (Class 1C). The device is packaged in a
3 mm × 3 mm LFCSP that uses an exposed paddle for excellent
thermal impedance.
The ADL5541 consumes 90 mA on a single 5 V supply and
is fully specified for operation from −40°C to +85°C.
A fully populated RoHS-compliant evaluation board is
available.
The ADL5542 is a companion part that offers a gain of 20 dB
in a pin-compatible package.
