MAX2683/MAX2684 Evaluation Kits
General Description
Features
The MAX2683/MAX2684 evaluation kits (EV kits) simplify
evaluation of the MAX2683/MAX2684 3.4GHz to 3.8GHz
downconverter mixers. The EV kits are fully assembled
and tested, allowing simple evaluation of all device func-
tions. All signal ports utilize SMA connectors, providing a
convenient interface to RF test equipment.
ꢀ Easy Evaluation of MAX2683/MAX2684
ꢀ All Critical Peripheral Components Included
ꢀ SMA Input and Output Signal Connectors
ꢀ RF Input Matched to 50Ω at 3600MHz
ꢀ IF Output Matched to 50Ω at 300MHz (MAX2683)
ꢀ IF Output Matched to 50Ω at 900MHz (MAX2684)
ꢀ Fully Assembled and Tested
The MAX2683/MAX2684 are downconversion mixers
intended for operation in the 3.4GHz to 3.8GHz frequen-
cy range. The MAX2683 is optimized for downconversion
to IF frequencies between 100MHz and 400MHz, and
allows high-side or low-side LO injection. The MAX2684
is optimized for IF frequencies between 800MHz to
1000MHz and only allows low-side LO injection. A logic-
level enabled LO frequency doubler allows the external
LO source to run at half frequency, or at full frequency if
disabled. As assembled, the MAX2683/MAX2684 EV kits
are configured for operation of the LO at half frequency.
A few simple component changes configure the EV kit
for operation of the LO at full frequency. In addition, an
external resistor allows adjustment of device linearity and
supply current.
