APPLICATIONS VCO buffers General purpose Tx/Rx amplification GENERAL DESCRIPTION The ADL5530 is a broadband, fixed-gain, linear amplifier that operates at frequencies up to 1000 MHz. The device can be used in a wide variety of wired and wireless devices, including cellular, broadband, CATV, and LMDS/MMDS applications. The ADL5530 provides a gain of 16.5 dB, which is stable over frequency, temperature, power supply, and from device to device. It achieves an OIP3 of 37 dBm with an output compression point of 21.8 dB and a noise figure of 3 dB. The ADL5530 operates with supply voltages of 3 V or 5 V with a supply current of 110 mA. The ADL5530 is fabricated on a GaAs pHEMPT process. The device is packaged in a 3 mm x 2 mm LFCSP that uses an exposed paddle for excellent thermal impedance. It operates from -40C to +85C. A fully populated evaluation board is also available. This amplifier is single-ended and internally matched to 50 with an input return loss of 11 dB. Only input/output ac-coupling capacitors, a power supply decoupling capacitor, and an external inductor are required for operation.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulates on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

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 an inductor connected to the RF output pin. The bias voltage should be decoupled using a 10 nF capacitor. A bias voltage of 5 V is recommended. However, the device is specified to operate down to 3 V with a slightly reduced compression point and a reduced noise figure. SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN Figure 23 shows the recommended land pattern for ADL5530. To minimize thermal impedance, the exposed paddle on the package underside should be soldered down to a ground plane along with Pin 8. If multiple ground layers exist, they should be stitched together using vias. Pin 1, Pin 3, Pin 4, Pin 5 and Pin 6 can be left unconnected, or can be connected to ground. Connecting these pins to ground slightly enhances thermal impedance. 3V TO 5V PIN 1 8 C5 10nF RFIN 1 NC GND 8 2 IN1 OUT1 7 0.46mm L1 470nH 0.33mm RF OUT 0.53mm C2 10nF 3 NC NC 6 4 NC NC 5 NC = NO CONNECT 0.33 mm 0.33mm Figure 21.

The board is powered by a single supply (between 3 V and 5 V). The components used on the board are listed in Table 6. Power can be applied to the board through clip-on leads (J5, J6), through an edge connector (P1), or through Jumper W1. Note that IN2, OUT2, T1, T2, C6, C7 and C10 have no function. Because Pin 1, Pin 3 and Pin 6 of ADL5530 are No Connects, these pins are grounded on this PCB (this has no effect on electrical performance).
