SMT MMIC Mixers and Amplifier
Hittite announces two SMT MMIC mixers and a medium power amplifier for applications in microwave radios, sensors, and test equipment from 6 to 31 GHz. Providing good wideband performance, the HMC144LC4 is a high IP3 double-balanced MMIC passive mixer which can be used as an up or downconverter from 6 to 20 GHz. Broadband operation and 35 dB LO to RF isolation are provided by on-chip baluns, which require no external components or DC bias. The HMC264LC3B is a 21 to 31 GHz sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier. The 2LO/RF isolation is excellent at 30 dB, eliminating the need for additional filtering. The HMC264LC3B operates from a single +3 or +4V bias, and requires only 4 to +4 dBm of LO drive. The RF and LO ports are DC blocked and matched to 50 Ω for ease of use while the IF covers DC to 6 GHz. Combining high gain and linearity, the HMC498LC4 is a high dynamic range GaAs PHEMT MMIC Medium Power Amplifier. Operating from 17 to 24 GHz, the amplifier provides 22 dB of gain and +26 dBm of saturated power at 23% PAE. Noise figure is 4 dB while output IP3 is +36 dBm enabling the HMC498LC4 to function as a low noise front.
