ADL5541: 50 MHz to 6 GHz RF/IF Gain Blocks

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 wired and wireless devices including cellular, GSM and WCDMA, and broadband applications.

The ADL5541 provides a gain of 15 dB, which is stable over frequency, temperature, power supply, and from device to device. It achieves an OIP3 of 40.9 dBm with an output compression point of 18.2 dBm and a noise figure of 3.5 dB at 900 MHz.

The amplifier is internally matched to 50 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 device operates with a supply voltage of 5 V with a supply current of 92 mA.

The ADL5541 is fabricated on an InGaP HBT process and has an ESD rating of 1000 V (Class 1C). The device is packaged in a 3 mm 3 mm LFCSP that uses an exposed paddle for excellent thermal impedance. It operates from -40¡ãC to +85¡ãC. A fully populated evaluation board is available.
