GENERAL DESCRIPTION
The ADL5535 is a 16 dB linear amplifier that operates at
frequencies up to 1 GHz. The device can be used in a wide
variety of cellular, CATV, military, and instrumentation
equipment.
The ADL5535 is fabricated on a GaAs HBT process and has an
ESD rating of ±2 kV (Class 2). The device is assembled in an
MSL-1 rated SOT-89 package that uses an exposed paddle for
excellent thermal impedance.
The ADL5535 provides the highest dynamic range available
from an internally matched IF gain block. This is accomplished
by providing extremely low noise figures and very high OIP3
specifications simultaneously across the entire 1 GHz frequency
range. The ADL5535 also provides extremely flat gain and P1dB
over frequency, which are stable over temperature, power supply,
and from device to device.
The ADL5535 consumes only 97 mA on a single 5 V supply and
is fully specified for operation from −40°C to +85°C.
The ADL5535 is also pin-compatible with the 20 dB gain
ADL5536. Fully populated evaluation boards are available
for each amplifier.
The device is internally matched to 50 Ω at the input and output,
making the ADL5535 very easy to implement in a wide variety
of applications. Only input/output ac coupling capacitors, power
supply decoupling capacitors, and an external inductor are
required for operation.

BASIC CONNECTIONS
The basic connections for operating the ADL5535 are shown in
Figure 15. Recommended components are listed in Table 5. The
input and output should be ac-coupled with appropriately sized
capacitors (device characterization was performed with 0.1 μF
capacitors). A 5 V dc bias is supplied to the amplifier through
the bias inductor connected to RFOUT (Pin 3). The bias voltage
should be decoupled using a 1 μF capacitor, a 1.2 nF capacitor,
and a 68 pF capacitor.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN
Figure 16 shows the recommended land pattern for the ADL5535.
To minimize thermal impedance, the exposed paddle on the
package underside, along with Pin 2, should be soldered to a
ground plane. If multiple ground layers exist, they should be
stitched together using vias. For more information about 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).

ACPR PERFORMANCE
Figure 17 shows a plot of the adjacent channel power ratio
(ACPR) vs. POUT for the ADL5535. The signal type used is a
single wideband code division multiple access (W-CDMA)
carrier (Test Model 1-64). This signal is generated by a very
low ACPR source. ACPR is measured at the output by a high
dynamic range spectrum analyzer that incorporates an instrument noise-correction function. At an output power level of
+8 dBm, ACPR is still very low at −65 dBc, making the device
suitable for use in driver applications.

ERROR VECTOR MAGNITUDE (EVM) PERFORMANCE
Error vector magnitude (EVM) is a measure used to quantify the
performance of a digital radio transmitter or receiver. A signal
received by a receiver has all constellation points at their ideal
locations; however, various imperfections in the implementation
(such as magnitude imbalance, noise floor, and phase imbalance)
cause the actual constellation points to deviate from their ideal
locations. The ADL5535 shows excellent performance when used
with higher-order modulation schemes, such as a 16 QAM.
Figure 18 illustrates the EVM performance of the ADL5535 when
driven with a 16 QAM 10 Msym/s signal. Degradation of the EVM
performance starts to occur at an output power of +12 dBm.

ADL5535
ADC DRIVING APPLICATION
The ADL5535 is a high linearity, fixed gain IF amplifier suitable
for use as an ADC driver. Figure 22 shows the schematic of the
ADL5535 driving the AD9268 16-bit analog-to-digital converter
(ADC). The ADL5535 has a single-ended input and output impedance of 50 Ω. A 1:1 impedance transformer, along with termination
resistors and series ferrite beads, are used to present a 50 Ω load
for the antialiasing filter interface. The filter interface between the
ADL5535 and the AD9268 is a sixth-order Butterworth low-pass
filter. The interface provides a 50 MHz, 1 dB bandwidth centered
around 175 MHz. Following the sixth-order filter, a shunt LC tank
circuit was inserted to further reduce the low frequency response
of the filter, giving more of a band-pass response to the filter.
The normalized wideband response is shown in Figure 19.
