Broadband sub-harmonic pumped mixer designed for cost-sensitive applications

Mon, 06/10/2013 - 4:58pm

M/A-COM Technology Solutions introduced a new Broadband Sub-Harmonic Pumped Mixer for cost sensitive applications covering the 14-32 GHz frequency range and IF frequencies from DC-7 GHz.

The MAMX-011009 is packaged in an ultra small 1.5x1.2 mm TDFN surface mount, allowing customers an easy, efficient and space-saving broadband solution. The mixer has a single RF port, requires no biasing and has excellent 2xLO and 3xLO isolation eliminating the need for extra filtering. The device requires +15dBm of LO power that can be easily attained by implementing the MAAM-011101, which is a single bias low cost 4-20 GHz buffer amplifier offered by MACOM.     

The MAMX-011009, can be used for up or down frequency conversion. The mixer integrates an 180° balanced diode topology that allows the LO to be injected at ½ the LO mixing frequency, which improves isolation and simplifies system requirements for the customer.

The table below outlines typical performance:
