FEATURES Fixed gain of 15 d B Operation up to 6 GHz Input/output internally matched to 50 Ω Integrated bias control circuit Output IP3 44 d Bm at 500 MHz 40 d Bm at 900 MHz Output 1 d B pression: 19.7 d Bm at 900 MHz Noise figure of 3.5 d B at 900 MHz Single 5 V power supply Small footprint 8-lead LFCSP Pin patible with 20 d B gain ADL5542 1 k V ESD (Class 1C) GENERAL DESCRIPTION The ADL5541 is a broadband 15 d B 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 d B, 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 d B 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 FUNCTIONAL BLOCK DIAGRAM INPUT RFIN 1 MATCH OUTPUT MATCH 8 RFOUT GND 2 BIAS CONTROL 7 GND GND 3 CB 4 6 GND 5 VPOS 06877-001 Figure 1. The ADL5541 is fabricated on an In Ga P HBT process and has an ESD rating of 1 k V (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 m A on a single 5 V supply and is fully specified for operation from - 40°C to +85°C. A fully populated Ro HS-pliant evaluation board is available. The ADL5542 is a panion part that offers a gain of 20 d B in a pin-patible package. Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
