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. Rev. B 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. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

Recommended components are listed in Table 5. The input and output should be ac-coupled with appropriately sized capacitors (device characterization was performed with 33 pF capacitors). A 5 V dc bias is supplied to the amplifier via GND (Pin 6) and through a biasing inductor connected to RFOUT (Pin 8). The bias voltage should be decoupled using a 1 µF capacitor, a 1.2 nF capacitor, and two 68 pF capacitors. 4.5 NOISE FIGURE (dB) 4.0 3.5 3.0 VCC 2.5 1 RFIN RFOUT 8 2 GND GND 7 3 GND GND 6 4 CB C2 33pF 2.0 200 RFOUT GND VPOS 5 Figure 20. Basic Connections For operation below 500 MHz, a larger biasing choke and ac coupling capacitors are necessary (see Table 5). Figure 21 shows input return loss, output return loss, and gain for frequencies between 200 MHz and 500 MHz.

To minimize thermal impedance, the exposed paddle on the package underside should be soldered down to a ground plane along with Pin 2, Pin 3, Pin 6, and Pin 7. If multiple ground layers exist, they should be stitched together using vias (a minimum of five vias is recommended).
