GENERAL DESCRIPTION

The ADL5606 is a broadband, two-stage, 1 W RF driver
amplifier that operates over a frequency range of 1800 MHz
to 2700 MHz. The device can be used in a wide variety of
wired and wireless applications, including ISM, MC-GSM,
W-CDMA, TD-SCDMA, and LTE.

The ADL5606 operates on a 5 V supply voltage and a supply
current of 362 mA. The driver also incorporates a fast power­up/power-down function for TDD applications, applications
that require a power saving mode, and applications that
intermittently transmit data.

The ADL5606 is fabricated on a GaAs HBT process and is
packaged in a compact 4 mm × 4 mm, 16-lead LFCSP that
uses an exposed paddle for excellent thermal impedance. The

ADL5606 operates from −40°C to +85°C. A fully populated

evaluation board tuned to 2140 MHz is also available.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress

Connect this pin to 5 V to disable the part. In the disabled state, the part draws approximately 4 mA
of current from the power supply and 1.4 mA from the DISABLE pin.

3 VCC

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.

ADL5606

APPLICATIONS INFORMATION

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.

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.

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.

For complete information about component values and spacing
for the different frequency tuning bands, see the ADL5606
Matching section.

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-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.

ADL5606 MATCHING

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. Tab le 6 lists the required matching
component values. Capacitors C
series (0402 size).

For all frequency tuning bands, the placement of C
is critical. Table 7 lists the recommended component spacing
for the various frequency tuning bands. The component spacing
is referenced from the center of the component to the edge of
the package.

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. P
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. P
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.

OUT

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

The ADL5606 is packaged in a thermally efficient 4 mm ×
4 mm, 16-lead LFCSP. The thermal resistance from junction
to air (θ
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

8.6 × 10
is 12.9°C/W, where the case is the exposed pad of the lead frame
package.

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.

EVALUATION BOARD

The schematic of the ADL5606 evaluation board is shown in
Figure 36. The evaluation board uses 25 mils wide, 50  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.

The evaluation board has a short, non-50  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.

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:

C3 = 10 pF
C5, C7 = 100 pF
C6, C8 = 0.01 μF
C9, C11 = 10 μF
C4, C10, C12, C13,

C12 = 100 pF, C13 = 0.01 μF, and C14 = 10 μF.

L1

The main bias for the ADL5606 comes through L1 to the output stage. L1 should be high

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

R1, R2 = 0 Ω
