T he amplifier can be operated down to +5 V with an OIP3 of
+22 dBm at 250 MHz and slightly reduced distortion perfor-
mance. T he wide bandwidth, high dynamic range and tempera-
ture stability make this product ideal for the various RF and IF
frequencies required in cellular, CAT V, broadband, instrumen-
tation and other applications.
T he AD8350 series are high performance fully-differential
amplifiers useful in RF and IF circuits up to 1000 MHz. T he
amplifier has excellent noise figure of 5.9 dB at 250 MHz. It
offers a high output third order intercept (OIP3) of +22 dBm
at 250 MHz. Gain versions of 15 dB and 20 dB are offered.
T he AD8350 is designed to meet the demanding performance
requirements of communications transceiver applications. It
enables a high dynamic range differential signal chain, with
exceptional linearity and increased common-mode rejection.
T he device can be used as a general purpose gain block, an
A-to-D driver, and high speed data interface driver, among
other functions. The AD8350 input can also be used as a single-
ended-to-differential converter.
T he AD8350 is offered in an 8-lead single SOIC package. It
operates from +5 V and +10 V power supplies, drawing 28 mA
typical. T he AD8350 offers a power enable function for power-
sensitive applications. T he AD8350 is fabricated using Analog
Devices’ proprietary high speed complementary bipolar process.
The device is available in the industrial (–40°C to +85°C)
temperature range.

CAUTIO N
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8350 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

AD8350
Reactive Matching
AP P LICATIO NS
In practical applications, the AD8350 will most likely be matched
using reactive matching components as shown in Figure 29.
Matching components can be calculated using a Smith Chart
and the AD8350’s S-Parameters (see T ables I and II) along
with those of the devices that are driving and loading it. T he S-
Parameters in T ables I and II assume a differential source and
load impedance of 50 Ω. Because the load impedance on the
output of the AD8350 affects the input impedance, a simulta-
neous conjugate match must be performed to correctly match
both input and output.
Using the AD 8350
Figure 27 shows the basic connections for operating the AD8350.
A single supply in the range +5 V to +10 V is required. T he
power supply pin should be decoupled using a 0.1 µF capacitor.
T he ENBL pin is tied to the positive supply or to +5 V (when
VCC = +10 V) for normal operation and should be pulled to
ground to put the device in sleep mode. Both the inputs and the
outputs have dc bias levels at midsupply and should be ac-coupled.
Also shown, in Figure 27, are the impedance balancing require-
ments, either resistive or reactive, of the input and output. With
an input and output impedance of 200 Ω, the AD8350 should
be driven by a 200 Ω source and loaded by a 200 Ω impedance.
A reactive match can also be implemented.

Figure 28 shows how the AD8350 can be driven by a single-
ended source. T he unused input should be ac-coupled to
ground. When driven single-ended, there will be a slight imbal-
ance in the differential output voltages. T his will cause an in-
crease in the second order harmonic distortion (at 50 MHz,
with VCC = +10 V and VOUT = 1 V p-p, –59 dBc was measured
for the second harmonic on AD8350-15).

Figure 30 shows how the AD8350 input can be matched for a
single-ended drive. T he unused input is ac-coupled to ground
using a low impedance (i.e., high value) capacitance. T he S-
Parameters for this configuration are shown in T ables III and
IV. T hese values assume a single-ended source impedance of
50 Ω and a differential load impedance of 50 Ω. As in the case
of a differential drive, a simultaneous conjugate match must be
performed to correctly match both input and output.
Evaluation Boar d
Figure 31 shows the schematic of the AD8350 evaluation board
as it is shipped from the factory. T he board is configured to
allow easy evaluation using single-ended 50 Ω test equipment.
T he input and output transformers have a 4-to-1 impedance
ratio and transform the AD8350’s 200 Ω input and output
impedances to 50 Ω. In this mode, 0 Ω resistors (R1 and R4)
are required.
T o allow compensation for the insertion loss of the transform-
ers, a calibration path is provided at T est In and T est Out. T his
consists of two transformers connected back to back.

T o drive and load the board differentially, transformers T 1 and
T 2 should be removed and replaced with four 0 Ω resistors
(0805 size); Resistors R1 and R4 (0 Ω) should also be removed.
T his yields a circuit with a broadband input and output imped-
ance of 200 Ω. T o match to impedances other than this, match-
ing components (0805 size) can be placed on pads C1, C2, C3,
C4, L1 and L2.
