The HMC260 is a passive double balanced mixer that can be used as an upconverter or downconverter between 14 and 26 GHz. The miniature monolithic mixer (MMIC) requires no external components or matching circuitry. The HMC260 provides excellent LO to RF and LO to IF suppression due to optimized Balun structures. The low cost mixer is ideal for high volume point to point and point to multipoint microwave radios applications. The mixer operates with LO drive levels above +9 dBm. Measurements were made with the chip mounted and bonded into in a 50 ohm test fixture. Data includes the parasitic effects of wire bond assembly. Connections were made with a 3 mil ribbon bond with minimal length (<12 mil).
