HMC258LC3B v00.0707 GaAs MMIC SUB-HARMONIC SMT MIXER, 14.5 - 19.5 GHz Typical Applications Features The HMC258LC3B is ideal for: Integrated LO Amplifier: 0 dBm Input • Point to Point Radios Sub-Harmonically Pumped (x2) LO • VSAT and SATCOM High 2LO/RF Isolation: >45 dB • Test & Measurement Equipment Wide IF Bandwidth: DC - 3.5 GHz • Military & Space No External Matching Required RoHS Compliant 3x3mm Ceramic SMT Package Functional Diagram General Description The HMC258LC3B is a 14.5 - 19.5 GHz surface mount sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier in a SMT leadless ceramic package. At 45 dB the 2LO to RF isolation eliminates the need for additional filtering. The LO amplifier is a single bias (+5V) two stage design with only 0 dBm driver requirement. The HMC258LC3B requires no external matching components, making it ideal for integrated subsystem applications. Utilizing the HMC258LC3B eliminates the need for wirebonding, thereby providing a consistent connection interface for the customer.

This pin is DC coupled and should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary IF frequency range. Any applied DC voltage to this pin will result in die non-function and possible die failure. 3 Vdd Power Supply for the LO Amplifier. An external RF bypass capacitor of 100 - 330 pF is required as close to the package as possible. 5 LO LO Port. This pin is AC coupled and matched to 50 Ohms. 7-9 N/C This pin may be connected to the housing ground or left unconnected. 11 RF RF Port. This pin is AC coupled and matched to 50 Ohms.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink.
