Analog Devices Inc. HMC219B GaAs MMIC Fundamental Mixers
Analog Devices HMC219B GaAs MMIC Fundamental Mixers are general-purpose, double balanced mixers in an ultra-miniature 8-lead, MINI_SO_EP package with an exposed pad. The HMC219B Mixers provide excellent LO to RF and LO to IF isolation thanks to its optimized balun structures. The HMC219B from Analog Devices offers typical local oscillator (LO) to radio frequency (RF) isolation at 40dB, LO to intermediate frequency (IF) at 35dB, and RF to IF isolation at 22dB.
Designers can use the HMC219B mixers as an upconverter, downconverter, bi-phase demodulator, or phase comparator. When used as a downconverter, the HMC219B mixers downconvert radio frequency (RF) between 2.5GHz and 7GHz to an intermediate frequency (IF) between DC and 3GHz. When used as an upconverter, the mixers upconvert IF between DC and 3GHz to RF between 2.5GHz and 7GHz. The mixer's consistent MMIC performance improves system operation and ensures regulatory compliance with HiperLAN, U-NII, and ISM.
Developed using a GaAs metal-semiconductor field-effect transistor (MESFET) process, the HMC219B requires no external components or matching circuitry. Furthermore, the HMC219B mixers eliminate the need for wire bonding and are compatible with high volume, surface-mount manufacturing techniques.
