Typical Applications

The HMC340LP5 Dual Mixer is ideal for:

• Wireless Infrastructure

• Wireless Local Loop

• Image Reject Mixer

• I/Q Modulator

• SSB Modulator

The HMC340LP5 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,

biphase (de)modulator, or phase comparator.

The mixer symmetry of the HMC340LP5 makes

it an ideal candidate for single sideband or image

rejection applications. The consistent MMIC

performance will improve system operation

and assure regulatory compliance. A low cost,

leadless 5x5 mm QFN surface mount package

(LP5) houses the dual MMIC mixer IC.
