30 MHz to 6 GHz RF/IF Gain Block ADL5545 Data Sheet FUNCTIONAL BLOCK DIAGRAM Fixed gain of 24.1 dB Broadband operation from 30 MHz to 6 GHz Input/output internally matched to 50 Ω Integrated bias control circuit OIP3 of 36.4 dBm at 900 MHz P1dB of 18.1 dBm at 900 MHz Noise figure of 2.9 dB at 900 MHz Single 5 V power supply Low quiescent current of 56 mA Wide operating temperature range of −40°C to +105°C Thermally efficient SOT-89 package ESD rating of ±1.5 kV (Class 1C) GND (2) ADL5545 BIAS 1 2 3 RFIN GND RFOUT 11385-001 FEATURES Figure 1. GENERAL DESCRIPTION The ADL5545 is a single-ended RF/IF gain block amplifier that provides broadband operation from 30 MHz to 6 GHz. The ADL5545 provides over 36 dBm of OIP3 using only 56 mA from a 5 V supply. The ADL5545 provides a gain of 24 dB, which is stable over frequency, temperature, power supply, and from device to device. The amplifier is offered in the industry-standard SOT-89 package and is internally matched to 50 Ω at the input and output, making the ADL5545 very easy to implement in a wide variety of applications. The only external components required are the input/output ac coupling capacitors, power supply decoupling capacitors, and dc bias inductor. Rev. A The ADL5545 is fabricated on an InGaP HBT process and has a high ESD rating of ±1.5 kV (Class 1C). The ADL5545 is also fully specified for operation across the wide temperature range of −40°C to +105°C. A fully populated RoHS-compliant evaluation board is available.

Recommended Land Pattern The land pattern on the ADL5545 evaluation board provides a measured thermal resistance (θJA) of 53°C/W. To measure θJA, the temperature at the top of the SOT-89 package is found with an IR temperature gun. Thermal simulation suggests a junction temperature 10°C higher than the top-of-package temperature. With additional measurements of the ambient temperature and I/O power, θJA can be determined. Rev. A | Page 15 of 20 ADL5545 Data Sheet OPERATION DOWN TO 30 MHz To operate the ADL5545 at frequencies below 100 MHz, a feedback network must be implemented between the input and output ports of the device to ensure stability. Figure 35 shows a sample configuration used to evaluate the device at frequencies below 100 MHz. Figure 36 to Figure 38 demonstrate the performance of the device in this configuration.
