18-45GHz GaAs MMIC Sub-Harmonic Mixer in SMT Package

Currently Viewing:

Broadcom’s AMMP-6545 is an easy-to-use broadband sub-harmonic mixer, with the LO injected at half the frequency of that required by a conventional mixer. MMIC includes an 180° balanced diode based mixer. The MMIC is fabricated using PHEMT technology. The surface mount package allows elimination of “chip & wire” assembly for lower cost. This MMIC is a cost effective alternative to multi-chip solution that have higher loss and complex assembly.
