Basic Connections Power Supply The voltage supply for the ADL5604, which ranges from 4.75 V to 5.25 V, should be connected to the VCC1 pin. The dc bias to the output stage is supplied through L1 and is connected to the RFOUT pin. Three decoupling capacitors, C6, C7, and C8, are used to prevent RF signals from propagating on the dc lines. The VBIAS and VCC2 pins are connected to the main supply voltage, VCC1, through the R2 and R5 resistors. Additional decoupling capacitors, C9, C10, C11, and C12, are required on the VCC2 and VBIAS pins. RF Input Interface Pin 1 and Pin 2 are the RF input pins for ADL5604. The RF input is easily matched with two or three components and a microstrip line used as an inductor. If additional inductance is required, C3 can be replaced with an inductor. See the ADL5604 Match section for the component values and spacing for the different frequency bands. RF Output Interface Pin 9 to Pin 12 are used as the RF output pins. The C5 shunt capacitor and the inductance from the microstrip line match RF output to 50 Ω. See the ADL5604 Match section for the component values and spacing for the different frequency bands. Power-Down Circuit Device U2 and its associated circuitry can be used to power down the ADL5604. To connect U2, remove the R2 resistor and place a 0 Ω resistor in place of R4. Rev. C | Page 15 of 23 ADL5604 Data Sheet ADL5604 MATCH The extended length allows the bias inductor to be placed close to the chip, where the impedance is lowest, while allowing a low inductance path to a shunt capacitor to ground. This extra length allows for alternative matching but is also included in the output match at all frequencies. Table 5 and Table 6 detail the component spacing and values for the input and output matching networks for the ADL5604 for the different frequencies. Figure 37 through Figure 42 show the matching networks. The ADL5604 is easily matched with three matching components and a microstrip line used as inductance. If spacing is tight, an external inductor can take the place of the microstrip line. The output match includes a short (76 mils, including the portion that is used as the pad for the chip) non 50 Ω line to accommodate the four output pins and allow for easier low inductance output matching. The pads for Pin 9 to Pin 12 are included on this microstrip line, as well as the pad for the L1 bias inductor. Table 5.

C | Page 18 of 23 Data Sheet ADL5604 ACPR AND EVM All adjacent channel power ratio (ACPR) and error vector magnitude (EVM) measurements were made using a single W-CDMA carrier and Test Model 1-64. The signal is generated by a very low ACPR source and is measured at the output by a high dynamic range spectrum analyzer. For ACPR measurements, the filter setting was chosen for low ACPR and for EVM measurements the low EVM setting was selected. The baseline composite EVM for the signal source used was around 0.5%. Highly linear amplifiers were used to measure ACPR and EVM at higher output power levels. Figure 26 shows the plot of ACPR vs. POUT at 946 MHz. Shown on the same plot is the system ACPR. For power levels up to 11 dBm, an ACPR of 65 dBc or better can be achieved. Figure 27 shows the ACPR vs. POUT at 1966 MHz. Shown on the same plot is the system ACPR. For power levels up to 11 dBm, an ACPR of 65 dBc or better can be achieved. Figure 28 shows ACPR vs. POUT at 2140 MHz. Shown on the same plot is the system ACPR. For power levels up to 12 dBm, an ACPR of 65 dBc or better can be achieved. Figure 29 shows the plot of EVM vs. POUT at 946 MHz. The EVM measured is less than 1% for power levels up to 15 dBm. LFCSP. The above thermal resistance numbers assume a minimum of nine thermal vias arranged in a 3 × 3 array with a diameter of 8 mils and a pitch of 16 mils. Because the top and bottom leads of the package are ground, the ground pattern on the evaluation board is extended on the top and bottom to improve thermal efficiency (see the Evaluation Board section). SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN Figure 43 shows the recommended land pattern for the ADL5604. To minimize thermal impedance, the exposed paddle on the 4 mm × 4 mm LFCSP package is soldered down to a ground plane along with Pin 5 to Pin 8 and Pin 13 to Pin 16. To improve thermal dissipation, nine thermal vias are arranged in a 3 × 3 array under the exposed paddle. Areas above and below the paddle are tied with regular vias. If multiple ground layers exist, they should be tied together using vias. For more information on land pattern design and layout, see the AN-772 Application Note, A Design and Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP). Figure 30 shows the EVM vs. POUT at 1966 MHz. The EVM measured is less than 1% for power levels up to 18 dBm. Figure 31 shows the EVM vs. POUT at 2140 MHz. The EVM measured is less than 1% for power levels up to 18 dBm. 16 13 RFIN When operated in the linear region, there is little or no contribution to EVM by the amplifier.

Recommended Land Pattern ADL5604 Data Sheet EVALUATION BOARD and are included in all matches. Figure 47 shows the close-up image of the recommended output pad. The evaluation board also has hash marks close to the input and output of the ADL5604, separated by 40 mils. The hash mark closest to the input is 127 mils from the chip, and the hash mark closest to the output is 20 mils from the chip. The schematic of the ADL5604 evaluation board is shown in Figure 44. This evaluation board uses 25 mils wide, 50 Ω traces and is made from IS410 material, with a 23 mils gap to ground. The evaluation board is tuned for operation at 2140 MHz. The inputs and outputs should be ac-coupled with appropriately sized capacitors; therefore, for low frequency applications, C1 and C2 may need to be increased. DC bias is provided to the output stage via an inductor connected to the RFOUT pin. A bias voltage of 5 V is recommended. The evaluation board has a short non 50 Ω line on its output to accommodate the four output pins and allow for easier low inductance output matching.

C3 provides dc blocking; therefore, a jumper is installed in place of C1. Input matching capacitors. The input match is set for 2140 MHz but is easily changed for other frequencies. C3 is set at a specific distance from C4 so that the microstrip line can act as inductance for part of the match. If space is at a premium, an inductor can take the place of the microstrip line. The ADL5604 is sensitive to the input match; therefore, the tolerance of these components and their placement must be tight. Output matching capacitor. The output match is set for 2140 MHz but is easily changed for other frequencies. The tolerance for this capacitor should be tight. C5 is set at a specific distance from the input; therefore, the microstrip line can act as inductance for part of the match. If space is at a premium, an inductor can take the place of the microstrip line. There is a short length of low impedance line on the output that is embedded in the match. The ADL5604 is less sensitive to the output match than the input match, but the tolerance still must be tight. The main bias for the ADL5604 comes through L1 to its output. L1 should be high impedance for the frequency of operation, while providing low resistance for the dc current. The evaluation board uses a Coilcraft 0603HP-16NX_H inductor. It is a 16 nH inductor, which provides some of the match at 2140 MHz. As the operating frequency gets lower, the inductance must increase, but as the inductance increases, the current is more limited for a 0603 package. R9 and R10 can be removed and L2 added to allow for low frequency operation. L2 has the footprint for a Coilcraft SLC7530D-101MLB (0.4 μH). Power supply decoupling. The need for power supply decoupling capacitance is based on the noise and potential for noise on the power supply. The smallest capacitor should be the closest to the ADL5604. The main bias that goes through RFOUT is the most sensitive to noise because the bias is connected directly to the output. R6 and R8 can be removed to eliminate any parasitic elements of VBIAS and VCC2 if a fast response time is required. The ADL5604 can be shut down using VBIAS alone or VBIAS and VCC2. The ADL5604 has a shutdown current of 13 mA when only VBIAS is used. The shutdown current is < 1 μA if VBIAS and VCC2 are used. However, VCC2 draws 5 mA when biased, setting the current drive capability of the shutdown controller. R2, R4, and R5 allow custom configuration of the shutdown. If VCC2 is used to shut down the ADL5604, 5 mA must be sourced when the part is enabled. U2, R1, and R3 are configured as a buffer to source the 5 mA. 08220-046 Component C1, C2 Figure 46.
