The HMC258 devices are sub-harmonically pumped (×2) single-ended monolithic microwave integrated circuit (MMIC) mixers with integrated LO amplifiers which can be used as upconverters or downconverters. The HMC258 devices are available in a chip (HMC258), an SMT leadless ceramic package (HMC258LC3B), and an SMT leadless chip carrier package (HMC258LM3). The HMC258 utilizes a GaAs metal semiconductor field effect transistor (MESFET) technology that results in a small overall chip area of 0.9 mm2. The 2LO to RF isolation is excellent, eliminating the need for additional filtering. The LO amplifier is a single bias (5 V) two stage design with only 0 dBm drive requirement.

A less stringent oscillator design is made possible by the low LO drive and sub harmonic nature of the HMC258 chip. All data is with the chip in a 50 Ω test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length less than 0.31 mm (<12 mils). The HMC258LC3B requires no external matching components, making it ideal for integrated subsystem applications. All data for the HMC258LM3 is with the nonhermetic, epoxy sealed LM3 packaged device mounted in a 50 Ω test fixture. Utilizing the HMC258LC3B or the HMC258LM3 eliminates the need for wire bonding, thereby providing a consistent connection interface for the customer.

Applications
