GENERAL DESCRIPTION The ADL5536 is a 20 dB linear amplifier that operates at frequencies up to 1 GHz. The device can be used in a wide variety of cellular, CATV, military, and instrumentation equipment. The ADL5536 provides the highest dynamic range available from an internally matched IF gain block. This is accomplished by providing extremely low noise figures and very high OIP3 specifications simultaneously across the entire 1 GHz frequency range. The ADL5536 also provides extremely flat gain and P1dB over frequency, which are stable over temperature, power supply, and from device to device. The device is internally matched to 50 Ω at the input and output, making the ADL5536 very easy to implement in a wide variety of applications. Only input/output ac coupling capacitors, power supply decoupling capacitors, and an external inductor are required for operation. The ADL5536 is fabricated on a GaAs HBT process and has an ESD rating of ±2 kV (Class 2). The device is assembled in an MSL-1 rated SOT-89 package that uses an exposed paddle for excellent thermal impedance. The ADL5536 consumes only 105 mA on a single 5 V supply and is fully specified for operation from −40°C to +85°C. The ADL5536 is also pin-compatible with the 16 dB gain ADL5535. Fully populated evaluation boards are available for each amplifier. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.

The signal type used is a single wideband code division multiple access (W-CDMA) carrier (Test Model 1-64). 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 instru- ment noise-correction function. At an output power level of +8 dBm, ACPR is still very low at −65 dBc, making the device suitable for use in driver applications. –30 –40 380MHz –50 –60 190MHz SOURCE POWER OUTPUT REFERRED –70 190MHz –80 380MHz SOURCE POWER OUTPUT REFERRED –90 –5 –3 –1 1 3 5 7 9 11 13 POUT (dBm) Figure 17.

A signal received by a receiver has all constellation points at their ideal locations; however, various imperfections in the implementation (such as magnitude imbalance, noise floor, and phase imbalance) cause the actual constellation points to deviate from their ideal locations. The ADL5536 shows excellent performance when used with higher-order modulation schemes, such as a 16 QAM. Figure 18 illustrates the EVM performance of the ADL5536 when driven with a 16 QAM 10 Msym/s signal. Degradation of the EVM performance starts to occur at an output power of +12 dBm. –20 –22 380MHz –24 –26 190MHz –28 –30 380MHz SOURCE POWER –32 OUTPUT REFERRED 190MHz SOURCE POWER –34 OUTPUT REFERRED –36 –38 –40 3 5 7 9 11 13 15 17 19 POUT (dBm) Figure 18.
