In the disabled state, the part draws approximately 4 mA of current from the power supply and 1.4 mA from the DISABLE pin. Under normal operation, this pin is connected to the power supply and draws a combined 362 mA of current. When this pin is grounded along with the VBIAS pin, the device is disabled and draws approximately 1.4 mA from the DISABLE pin. Applying 5 V to this pin enables the bias circuit. When this pin is grounded, the device is disabled. No Connect. Do not connect to this pin. RF Output. DC bias is provided to this pin through an inductor that is connected to the 5 V power supply. The RF path requires a dc blocking capacitor. The exposed paddle should be soldered to a low impedance electrical and thermal ground plane.

BASIC LAYOUT CONNECTIONS The basic connections for operating the ADL5606 are shown in Figure 31. The RF matching components correspond to the 2140 MHz frequency tuning band. RF Output Interface Pin 9 to Pin 12 are the RF output pins. The RF output requires only one shunt capacitor and a microstrip line used as an inductor to match to 50 Ω. For complete information about component values and spacing for the different frequency tuning bands, see the ADL5606 Matching section. Power Supply The voltage supply for the ADL5606, which ranges from 4.75 V to 5.25 V, should be connected to the VCC1 test pin. The dc bias to the output stage is supplied through L1 and is connected to the RFOUT pin. Three decoupling capacitors (C7, C8, and C9) are used to prevent RF signals from propagating on the dc lines. The VBIAS and VCC pins can be directly connected to the main supply voltage. Additional decoupling capacitors (C5, C6, and C11) are required on the VCC pin. Power-Down The ADL5606 can be disabled by connecting the DISABLE pin to 5 V. When disabled, the ADL5606 draws approximately 4 mA of current from the power supply and 1.4 mA from the DISABLE pin. Decoupling Capacitor C3 is recommended to prevent the propagation of RF signals. To completely shut down the device, connect the VCC pin, the VBIAS pin, and the VCC1 test pin to ground. In this state, the part draws approximately 1.4 mA from the DISABLE pin. RF Input Interface Pin 1 is the RF input pin for the ADL5606. The RF input is easily matched with one capacitor, in a series or shunt configuration, and a microstrip line used as an inductor. For the 1960 MHz and 2140 MHz frequency tuning bands, a shunt capacitor is used to match the input to 50 Ω; for the 2630 MHz frequency tuning band, a series capacitor is used.

Recommended Components for Basic Connections The RF input and output of the ADL5606 can be easily matched to 50 Ω with at most one external component and the microstrip line used as an inductor.

Frequency (MHz) 1930 to 1990 2110 to 2170 2570 to 2690 For all frequency tuning bands, the placement of CIN and COUT is critical.

ADL5606 Match Parameters, 2630 MHz Frequency Tuning Band Rev. 0 | Page 14 of 20 ADL5606 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; for EVM measurements, the low EVM setting was selected. The spectrum analyzer incorporates an instrument noise correction function, and highly linear amplifiers were used to boost the power levels for ACPR measurements. Figure 26 shows ACPR vs. POUT at 1960 MHz and 2140 MHz. For power levels up to 18 dBm, an ACPR of 50 dBc or better can be achieved at 1960 MHz and 2140 MHz. Figure 27 shows EVM vs. POUT at 1960 MHz and 2140 MHz. The EVM measured is 0.5% for power levels up to 18 dBm at 1960 MHz and 2140 MHz. The baseline composite EVM for the signal source was approximately 0.5%. When operated in the linear region, there is little or no contribution to EVM by the amplifier. For optimal performance, it is recommended that the thermal vias be filled with a conductive paste of the equivalent thermal conductivity specified earlier in this section; alternatively, an external heat sink can be used to dissipate heat quickly without affecting the die junction temperature. It is also recommended that the ground pattern be extended above and below the device to improve thermal efficiency (see Figure 35). SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN Figure 35 shows the recommended land pattern for the ADL5606. To minimize thermal impedance, the exposed paddle on the 4 mm × 4 mm LFCSP is soldered to a ground plane along with Pin 5 to Pin 8 and Pin 13 to Pin 16. To improve thermal dissipation, 25 thermal vias are arranged in a 5 × 5 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 about land pattern design and layout, see the AN-772 Application Note, A Design and Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP). THERMAL CONSIDERATIONS For the best thermal performance, it is recommended that as many thermal vias as possible be added under the exposed pad of the LFCSP. The thermal resistance values assume a minimum of 25 thermal vias arranged in a 5 × 5 array with a via diameter of 8 mils, via pad of 16 mils, and a pitch of 20 mils. The vias are plated with copper, and the drill hole is filled with a conductive copper paste.

The thermal resistance from junction to air (θJA) is 52.9°C/W. The thermal resistance for the product was extracted assuming a standard 4-layer JEDEC board with 25 copper plated thermal vias. The thermal vias are filled with conductive copper paste (AE3030 with thermal conductivity of 7.8 W/mK and thermal expansion α1 of 4 × 10−5/°C and α2 of 8.6 × 10−5/°C). The thermal resistance from junction to case (θJC) is 12.9°C/W, where the case is the exposed pad of the lead frame package. Figure 35. Recommended Land Pattern ADL5606 EVALUATION BOARD The evaluation board has a short, non-50 Ω line on its output to accommodate the four output pins and to allow for easier low inductance output matching. The pads for Pin 9 to Pin 12 are included on this microstrip line and are included in all matches. The evaluation board uses numbers as identifiers to aid in the placement of matching components at both the RF input and RF output of the device. Figure 37 and Figure 38 show images of the board layout. The schematic of the ADL5606 evaluation board is shown in Figure 36. The evaluation board uses 25 mils wide, 50 Ω traces and is made from IS410 material with a 20 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, the value of C1 and C2 may need to be increased. DC bias is provided to the output stage via an inductor (L1) connected to the RFOUT pin. A bias voltage of 5 V is recommended.

Power supply decoupling capacitors. Power supply decoupling capacitors are required to filter out the high frequency noise on the power supply. The smallest capacitor should be the closest to the ADL5606. The main bias that goes through RFOUT is the most sensitive to noise because the bias is connected directly to the RF output. For the 1960 MHz and 2140 MHz frequency tuning bands, Capacitors C12, C13, and C14 are open; for the 2630 MHz frequency tuning band, it is recommended that the bypassing capacitors be added as follows: C12 = 100 pF, C13 = 0.01 μF, and C14 = 10 μF. Input matching capacitor. To match the ADL5606 at the 2140 MHz frequency tuning band, Shunt Capacitor CIN is required at a distance of 268 mils. If space is at a premium, an inductor can take the place of the microstrip line. Output matching capacitor. COUT is set at a specific distance from the device so that the microstrip line can act as inductance for the matching network (see Table 7). If space is at a premium, an inductor can take the place of the microstrip line. A short length of low impedance line on the output is embedded in the match. The main bias for the ADL5606 comes through L1 to the output stage. 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-18NX_LU inductor; this 18 nH inductor provides some of the match at 2140 MHz. To provide bias to all stages through just one supply, set R1 and R2 to 0 Ω, and leave R4 and R5 open. To provide separate bias to stages, set R1 and R2 to open and R4 and R5 to 0 Ω. The paddle should be connected to both thermal and electrical ground.
