Functional Diagram
General Description
The HMC340LP5(E) is a double balanced dual mixer
covering 1.7 - 4.5 GHz RF/LO range. This passive
MMIC mixer is constructed of GaAs Schottky diodes
and on-chip baluns. The device can be used as an
upconverter, downconverter, bi-phase (de)modulator,
or phase comparator. The mixer symmetry of the
HMC340LP5(E) make it ideal for combining with
external hybrids to implement a single sideband
upconverter or image reject downconverter assembly.
The consistent MMIC performance will improve system
operation and assure regulatory compliance. A RoHS
compliant, leadless 5x5 mm QFN surface mount
package (LP5) houses the dual MMIC mixer IC.
