GENERAL DESCRIPTION
The ADL5602 is a broadband 20 dB linear amplifier that operates at frequencies up to 4 GHz. The device can be used in a wide variety of cellular, CATV, military, and instrumentation equipment. The ADL5602 provides the highest dynamic range available from an internally matched gain block. This is accomplished by providing extremely low noise figures and very high OIP3 specifications simultaneously, across the entire 4 GHz frequency range. The ADL5602 provides a gain of 20 dB, which is stable over frequency, temperature, power supply, and from device to device. The device is internally matched to 50 at the input and output, making the ADL5602 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 ADL5602 is fabricated on an InGaP HBT process and has an ESD rating of 1.5 kV (Class 1C). The device is available in a thermally efficient SOT-89 package. The ADL5602 consumes 89 mA on a single 5 V supply and is fully specified for operation from -40C to +85C. A fully populated RoHS-compliant evaluation board is available.

ADL5602 BASIC CONNECTIONS
The basic connections for operating the ADL5602 are shown in Figure 15. Recommended components are listed in Table 5. The input and output should be ac-coupled with appropriately sized capacitors (device characterization was performed with 0.1 F capacitors). A 5 V dc bias is supplied to the amplifier through the bias inductor connected to RFOUT (Pin 3). The bias voltage should be decoupled using a 1 F capacitor, a 1.2 nF capacitor, and a 68 pF capacitor.
GND VCC C6 1F
SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN
Figure 16 shows the recommended land pattern for the ADL5602. To minimize thermal impedance, the exposed paddle on the package underside should be soldered down to a ground plane along with Pin 2. If multiple ground layers exist, they should be stitched together using vias. For more information on land pattern design and layout, refer to AN-772 Application Note, A Design and Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP).

ADL5602 W-CDMA ACPR PERFORMANCE
ACPR AT 5MHz CARRIER OFFSET (dBc)
Figure 17 shows a plot of adjacent channel power ratio (ACPR) vs. POUT for the ADL5602. The signal type being used is a single 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, which incorporates an instrument noise correction function. The ADL5602 achieves an ACPR of -75 dBc at -5 dBm output, at which point device noise and not distortion is beginning to dominate the power in the adjacent channels. At an output power of +5 dBm, ACPR is still very low at -61 dBc, making the device particularly suitable for PA driver applications.
