applications such as high bit rate transmitters and
receivers which may be used in Point-to-Point,
Satcom or LAN applications. The mixer has 8 dB of
conversion loss and 23 dBm of input intercept point
(IIP3).
This mixer can be used for either lower sideband
(LSB) or upper sideband (USB) mixing. Two of
these mixers can be combined in a quadrature
configuration for image rejection.
Positive bias voltage (< 1 V) can be applied to the
LO or the V
G
(optional) pin to reduce LO drive
requirements. The V
G
pin is internally bypassed.
Positive bias voltage (< 1 V) can also be applied to
the IF pin to optimize device linearity.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
Class 1A (HBM) devices.
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. MACOM does not recommend sustained operation near these
survivability limits.
7.
Operating at nominal conditions with T
J
≤ +150°C will ensure
MTTF > 1 x 10
6
hours.

MAMX-011021
High Linearity Mixer
5 - 35 GHz
Application Information
The MAMX-011021 is designed to be an economical
and easily used mixer. The ultra small size and
passive structure allows easy placement on any
system board.
Rev. V1
Optional DC Biasing
As shown in the Application Schematic, the
MAMX-011021 does not require DC biasing. The
V
G
pin should be left open if not used for biasing.
Optionally, applying up to 0.5 V bias through the V
G
pin (or through the LO pin) can reduce the mixer
LO drive requirement (in general, reducing LO
drive will reduce input IP3). Any DC voltage applied
through the V
G
pin will appear on the LO pin, so
when biasing V
G
it may be necessary to have a DC
blocking capacitor on the LO pin. See the Optional
Biasing Schematic.
Input IP3 may be increased by applying small
amounts of voltage (V
D
< 1.0 V) to the IF pin. The
IF pin will draw a small current (typically less than
20 mA) when V
D
is positive so bias through an
inductor or resistor (accounting for the voltage
drop). The inductor or the resistor should have an
impedance large compared to 50
Ω
at the IF
frequency (typically at least 200
Ω).

It is recommended that the total ground (common
mode) inductance not exceed 0.03 nH. This is
equivalent to three 8-mil (200 µm) diameter vias
under the device on an 8-mil thick PC board
combined with vias included in the ground plane
around the package.
