ADL5541

Data Sheet FEATURES Fixed gain of 15 dB Operation up to 6 GHz Input/output internally matched to 50 Ω Integrated bias control circuit Output IP3 44 dBm at 500 MHz 40 dBm at 900 MHz Output 1 dB compression: 19.7 dBm at 900 MHz Noise figure of 3.5 dB at 900 MHz Single 5 V power supply Small footprint 8-lead LFCSP Pin compatible with 20 dB gain ADL5542 1 kV ESD (Class 1C) 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. 20 MHz to 6 GHz RF/IF Gain Block ADL5541 FUNCTIONAL BLOCK DIAGRAM INPUT RFIN 1 MATCH OUTPUT MATCH 8 RFOUT GND 2 BIAS CONTROL 7 GND GND 3 CB 4 ADL5541 6 GND 5 VPOS 06877-001 Figure 1. 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 ...
