GENERAL DESCRIPTION The ADL5534 contains two broadband, fixed-gain, linear amplifiers and operates at frequencies up to 500 MHz. The device can be used in a wide variety of equipment, including cellular, satellite, broadband, and instrumentation equipment. The ADL5534 has a fixed gain of 20 dB, which is stable over frequency, temperature, power supply, and from device-to- device. The amplifiers are single-ended and internally matched to 50 Ω. Only input/output ac-coupling capacitors, power supply decoupling capacitors, and an external bias inductor are required for operation of each amplifier. The ADL5534 is fabricated on a GaAs HBT process. The device is packaged in a 16-lead 5 mm × 5 mm LFCSP that uses an exposed paddle for excellent thermal impedance. The ADL5534 consumes 98 mA of current per amplifier on a single 5 V supply, and is fully specified for operation from −40°C to +85°C. A similar amplifier, ADL5531 (available from Analog Devices, Inc.) is the 20 dB gain single-channel version. Fully populated evaluation boards for both the ADL5531 and ADL5534 are available.

The basic connections for operating the ADL5534 are shown in Figure 16. Recommended components are listed in Table 5. The inputs and outputs should be ac-coupled with appropriately sized capacitors (device characterization was performed with 10 nF capacitors). DC bias is provided to the amplifier via the

L1 and L2 inductors connected to the RFOUT1 and RFOUT2 pins. The recommended inductors for L1 and L2 are Coilcraft, 1008CS-471XJLC or equivalent. The bias voltage should be decoupled using 10 nF and 1 μF capacitors. A bias voltage of 5 V is required.

Figure 17. Connections for Operating as a Balanced Amplifier

USING BALUNS TO COMBINE BOTH AMPLIFIERS INTO A SINGLE AMPLIFIER

The ADL5534 is ideal for use in a balanced amplifier confi-guration. To accomplish this, flux-coupled RF transformers with a 2:1 impedance ratio can be used for wide band operation. Alternatively, a balun can be constructed using lumped element components for operation over a narrow frequency range. Figure 17 shows the necessary connections for configuring the ADL5534 for operation as a balanced amplifier. Figure 18 shows the performance of the ADL5534 operating in a balanced configuration. 0

ADC DRIVING APPLICATION The ADL5534 is a high linearity, fixed gain IF amplifier suitable for use as an ADC driver. The ADL5534 has a differential input and output impedance of 100 Ω. A flux-coupled RF transformer with a 2:1 impedance ratio was used to perform the single-ended-to-differential conversion at the input of the ADL5534. The interface between the ADL5534 and the AD9640 is a third-order low pass filter presenting a 100 Ω differential impedance to the source and load. The ADL5534 must be ac-coupled to prevent dc bias from entering the inputs of the ADC. Capacitors of 100 pF were chosen to reduce any low frequency noise coming from the ADL5534 and provide dc blocking. The measured results for this interface shows 0.5 dB insertion loss for a 20 MHz bandwidth centered around 92 MHz. The wideband response for the interface is shown in Figure 20. The single-tone results in Figure 21 show an SNR of 69.3 dB and an SFDR of 82 dBc. The two-tone results in Figure 22 show an IMD3 of −80.5 dBc and an SFDR of 78 dBc.

SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN Figure 23 shows the recommended land pattern for ADL5534. To minimize thermal impedance, the exposed paddle on the package underside should be soldered down to a ground plane. If multiple ground layers exist, they should be stitched together using vias. Pin 1 to Pin 4, Pin 6, Pin 9 to Pin 11, and Pin 14 to Pin 15 can be left unconnected, or can be connected to ground. Connecting these pins to ground improves device-to-device isolation and slightly enhances thermal impedance. For more information on land pattern design and layout, refer to the AN-772 Application Note, A Design and Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP).

EVALUATION BOARD Figure 24 shows the schematic for the ADL5534 evaluation board. The board is powered by a single 5 V supply. The components used on the board are listed in Table 6. Transformers (T1 and T2) are provided so the ADL5534 can be configured as a balanced amplifier. Applying 5 V to

VPOS biases the amplifier corresponding to RFIN1 and RFOUT1. Applying 5 V to VPOS1 biases the amplifier corresponding to RFIN2 and RFOUT2. To bias both amplifiers from a single supply, connect 5 V to VPOS or VPOS1 and attach a jumper across W3.
