Functional Diagram
General Description
The HMC711LC5 is a GaAs MMIC sub-harmonic
upconverter in a leadless RoHS compliant QFN SMT
ceramic package. This compact upconverter provides
a small signal conversion gain of 15 dB and wide IF
bandwidth of DC - 3.5 GHz. The HMC711LC5 utilizes
a mixer which is driven by an active x2 multiplier and
followed by a high linearity amplifier. The HMC711LC5
is a much smaller alternative to hybrid style subharmonic upconverter assemblies and it eliminates the
need for wire bonding by allowing the use of surface
mount manufacturing techniques.
Electrical Specifications, IF = 1900 MHz, LO = +4 dBm, Vdd1, Vdd2, Vdd3 = +5V [1][2]

N/C
The pins are not connected internally; however, all data shown herein was
measured with these pins connected to RF/DC ground externally.
4, 6, 18,

GND
These pins and the package bottom must be connected to RF/DC ground.

IFIN
This pin is DC coupled. For applications not requiring operation to DC,
this port should be DC blocked externally using a series capacitor whose
value has been chosen to pass the necessary IF frequency range. For
operation to DC, this pin must not source or sink more than 2 mA of current or part non-function and possible part failure will result.

123835 Evaluation Board
The circuit board used in the final application
should use RF circuit design techniques. Signal
lines should have 50 Ohm impedance while the
package ground leads and exposed paddle should
be connected directly to the ground plane similar
to that shown. A sufficient number of via holes
should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
