Typical Applications

The HMC340LP5 / HMC340LP5E Dual Mixer is ideal

for:

• Wireless Infrastructure

• Wireless Local Loop

• Image Reject Mixer

• I/Q Modulator

• SSB Modulator

The

HMC340LP5

&

HMC340LP5E

are

double-

balanced dual mixers 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 sym-

metry of the HMC340LP5 & HMC340LP5E make 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.
