Covering a radio band from 14.5 to 19.5 GHz, the HMC258LC3B sub-harmonically pumped (x2) MMIC mixer is housed in a 3 x 3-mm leadless RoHS-compliant ceramic SMT package. The device features a wide IF bandwidth of dc to 3.5 GHz, and high 2LO to RF isolation of 45 dB, which eliminates the need for additional filtering.

The HMC258LC3B features an LO amplifier with a nominal 0-dBm drive requirement and requires no external matching components, making it ideal for integrated subsystem applications. The RF and LO ports of the device are dc blocked and matched to 50 Ω for design convenience, and the device consumes only 42 mA from a 5-V supply.
