30 MHz to 6 GHz RF/IF Gain Block ADL5544 Data Sheet FUNCTIONAL BLOCK DIAGRAM Fixed gain of 17.4 dB Broadband operation from 30 MHz to 6 GHz Input/output internally matched to 50 Ω Integrated bias control circuit OIP3 of 34.9 dBm at 900 MHz P1dB of 17.6 dBm at 900 MHz Noise figure of 2.9 dB at 900 MHz Single 5 V power supply Low quiescent current of 55 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) ADL5544 BIAS 1 2 3 RFIN GND RFOUT 11384-001 FEATURES Figure 1. GENERAL DESCRIPTION The ADL5544 is a single-ended RF/IF gain block amplifier that provides broadband operation from 30 MHz to 6 GHz. The ADL5544 provides over 34 dBm of OIP3 using only 55 mA from a 5 V supply. The ADL5544 provides a gain of 17 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 ADL5544 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. 0 The ADL5544 is fabricated on an InGaP HBT process and has a high ESD rating of ±1.5 kV (Class 1C). The ADL5544 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.

Basic Connections S11, S11, S22, S22, S12, S12, A 5 V dc bias is supplied to the amplifier through the bias inductor connected to RFOUT (Pin 3). The bias voltage must be decoupled using 100 pF, 1 nF, and 10 μF power supply decoupling capacitors. The typical current consumption for the ADL5544 is 55 mA. At low and high frequencies, the device exhibits improved performance with the suggested setup configuration listed in Table 6.

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.

The signal type used is a single wideband code division multiple access (W-CDMA) carrier (Test Model 1-64) at 2140 MHz. This signal is generated by a very low ACPR source. ACPR is measured at the output by a high dynamic range spectrum analyzer that incorporates an instrument noise-correction function. Figure 34.
