The HMC259 is a broadband sub-harmonically pumped (x2) balanced MMIC passive mixer designed by Hittite Corporation. It has a wide frequency range of 28-40GHz and LO frequency range of 14-20GHz. It is suitable for 38GHz point-to-point radios, Local Multi-Point Distribution Systems (LMDS), and SATCOM applications.
The HMC259 is a broadband sub-harmonically pumped (x2) balanced MMIC passive mixer designed for use as an upconverter or downconverter in the 28-40 GHz frequency range. It utilizes a GaAs MESFET process to achieve a small overall chip area of 1.9mm², making it ideal for 38 GHz radios, LMDS, and SATCOM applications.
