Functional Diagram
General Description
The HMC258LM3 is a 14 - 20 GHz surface mount sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier in a SMT leadless chip carrier package. The 2LO to RF isolation is an excellent 40 dB, eliminating the need for additional filtering. The LO amplifier is a single bias (+5V) two stage design with only 0 dBm drive requirement. All data is with the non-hermetic, epoxy sealed LM3 packaged device mounted in a 50 ohm test fixture. Utilizing the HMC258LM3 eliminates the need for wirebonding, thereby providing a consistent connection interface for the customer.
