General Description
Benefits and Features
The MAX2091 monolithic SiGe BiCMOS upconverter IC
integrates an analog variable-gain amplifier (VGA) with
an upconverting mixer stage and image filter. The device
amplifies IF signals in the 250MHz to 450MHz range
before mixing them with an LO signal. The resulting
1735MHz to 1935MHz upconverted signal is then filtered
on-chip as the final stage of signal conditioning. For a
broadband variant that does not include the image filter,
refer to the MAX2091B.

S High Linearity
+24.5dBm OIP3
+12dBm Output -1dB Compression Point
S 23dB Gain
The analog attenuator is controlled by an external analog
control voltage. Device features include 23dB gain (no
attenuation), 5.4dB NF (no attenuation, including attenu-
ator insertion loss), and +24.5dBm OIP3. Each of these
features makes the MAX2091 an ideal upconverter for
numerous transmitter applications. When paired with the
MAX2092 RF VGA, a complete 2-chip IF-RF signal con-
ditioning solution is possible for microwave point-to-point
transmitter applications.

S 5.4dB Noise Figure (Includes Attenuator
Insertion Loss)
S 0.25dB Gain Variation Over 100MHz Bandwidth
S Analog Attenuator Controlled with External

S Alarm Circuit with Adjustable Threshold
S 20dB Image Rejection at 1135MHz RF Frequency
The MAX2091 operates from a single 5V supply, and is
available in a compact 20-pin TQFN package (5mm x
5mm) with an exposed pad. Electrical performance is
guaranteed over the extended temperature range from

Detailed Description
Applications Information
The MAX2091 is a monolithic SiGe BiCMOS upconverter
IC that integrates an analog variable-gain amplifier, an
upconverting mixer stage, and image filter. The device
amplifies IF signals in the 50MHz to 500MHz range
before mixing them with an LO signal. The resulting
1735MHz to 1935MHz upconverted signal is then filtered
on-chip as the final stage of signal conditioning.
Modes of Operation
The MAX2091 can operate in several different modes, as
summarized in Table 1.
VGA/Mixer-Only Mode Operation
VGA/mixer-only mode operation consists of setting
CTRL1 = logic 1 and CTRL2 = logic 0 and applying a DC
value to PLVLSET between 0 and 2.5V DC, to manually
adjust the IF attenuator and subsequently the RF_OUT
power. The output power at RF_OUT increases at a
rate of 19.5dB/V as PLVLSET is increased when IF_IN
is driven with a fixed input power between -25dBm and
+5dBm. The error amplifier and alarm are powered off
in this mode, reducing the supply current (10mA typ). In
VGA/mixer-only mode, components R5, R7, C8, C9, and
C16 are left unpopulated.
The analog attenuator is controlled by an external analog
control voltage. Device features include 23dB gain (no
attenuation), 5.4dB NF (no attenuation, including attenu-
ator insertion loss), and +24.5dBm OIP3. Each of these
features makes the MAX2091 an ideal upconverter for
numerous transmitter applications. When paired with the
MAX2092 RF VGA, a complete 2-chip IF-RF signal con-
ditioning solution is possible for microwave point-to-point
transmitter applications.

Closed-ALC Mode Operation
Closed-ALC mode operation consists of setting CTRL1
= CTRL2 = logic 1. The voltage on PLVLSET is set
externally to provide -3dBm at RF_OUT for IF_IN power
between -25dBm and +5dBm. For other input power
ranges, PLVLSET can be externally driven to any DC
value between 0 and 2.5V, such that the desired output
power is present at RF_OUT (see the Typical Application
Circuit). An error amplifier compares the external detec-
tor’s voltage to that of PLVLSET, and drives the IF attenu-
ator in servo fashion until the error amplifier’s differential
input error voltage is near zero. The servo loop acts to
maintain the input power level to the mixer as the power
level at IF_IN changes. Ideally, a detector with an output
voltage range of 0.1V to 2.4V DC is recommended, but
the MAX2091 can operate with any detector whose out-
put ranges from 0 to 2.5V DC (with the coupling network
at IF_OUT already taken into account).
-25dBm to +5dBm. See Figure 1 for details. Contact
the factory for additional details surrounding Maxim’s
MAX2091 and MAX2092 reference design.
Control Inputs
The MAX2091 has four control inputs: CTRL1, CTRL2,
ALM_THRES, and PLVLSET. VCC must be present
before voltages are applied to these pins. In cases where
this is not possible, a 200I resistor must be included in
series with the control inputs to limit on-chip ESD diode
conduction. CTRL1 and CTRL2 are 3V logic controls and
cannot be driven from 5V logic. In the case where no
logic control is available and a logic-high is required, a
voltage-divider can be used from the 5V VCC supply to
produce the 3V logic-high.
VGA Output Pad
As shown in Figure 1 and the Typical Application Circuit,
provisions have been made to allow for the placement of
a Tee attenuator between the VGA output and the mixer
input. A default value of 2.5dB is used within the applica-
tion circuit, although any desired value can be chosen.
Alternatively, the attenuator can be replaced by a sim-
ple equalizer circuit if additional frequency gain-slope
correction is desired over wider bands of operation.
When used in conjunction with the MAX2092 RF VGA, a
nominal RF signal level of approximately -3dBm output
from the MAX2091 is recommended. With this specific
level setting, the complete MAX2091 and MAX2092 cas-
cade can yield a constant RF output power of at least
-20.5dBm to +5dBm over an IF input power range of
25

50MHz to 500MHz Analog VGA, 1735MHz to 1935MHz
Upconverting Mixer with Image Filtering, Threshold
Alarm Circuit, and Error Amplifier for Level Control
Additionally, a lowpass filter can be used between the
VGA output and the mixer input to reduce possible image
noise (RF + LO) at the VGA output from being downcon-
verted to the mixer output. Contact the factory for details.
The mixer is designed to operate with LO+ signal levels
between -10dBm and -4dBm and with LO- grounded. In
cases where V
is applied to the MAX2091 and LO+
CC
is below approximately -15dBm, the mixer’s LO driver
could produce undesired spurious at RF_OUT. In such
a case, applying -10dBm to -4dBm to LO+ returns the
mixer to proper operation. To eliminate the possibility
of spurious at RF_OUT with invalid LO+ signal levels,
power-down mode can be asserted (CTRL1 = CTRL2 =
logic 0) to disable RF_OUT.
Alarm Operation
The alarm output (ALM) remains in a logic-high state,
while DET_IN is above 1.35V nominally. ALM_THRES has
135kIinput resistance and is set internally to 1.35V (typ),
such that ALM triggers when DET_IN is below 1.35V.
Alternatively, the voltage on ALM_THRES can be exter-
nally driven to allow alternative power-level trip points.
The ALM comparator has a typical hysteresis of 29mV.
Layout Considerations
The pin configuration of the MAX2091 is optimized to
facilitate a very compact physical layout of the device and
its associated discrete components. The exposed pad

(EP) of the MAX2091’s 20-pin TQFN package provides a
low thermal-resistance path to the die. It is important that
the PCB on which the MAX2091 is mounted be designed
to conduct heat from the EP. In addition, provide the EP
with a low-inductance path to electrical ground. The EP
must be soldered to a ground plane on the PCB, either
directly or through an array of plated via holes.
