Wideband RF mixers simplify & speed designs, to 42 GHz
Over 10 discrete components, ADI estimates, would be required to cover this same frequency range, as compared to what can be achieved with these devices without any compromise in performance. ADI’s HMC819x mixers are the only wideband solutions available in a standard SMT package, allowing them to be integrated efficiently.
The HMC819x series’ RF and LO (local oscillator) bandwidth of 2.5 to 42 GHz along with wide IF bandwidth enable military or test and measurement applications to simplify design implementation while still maintaining RF performance. The series achieves isolation on the order of 35 dB or greater for both LO to RF and LO to IF isolation and greater than 20 dB of RF to IF isolation. The inherent I/Q architecture of the mixers accomplishes image/sideband rejection of 25 dBc or greater without the use of expensive external filtering. Input IP3 greater than 20 dBm is realized over the wide bandwidth while maintaining low conversion loss and high dynamic range. Well-matched LO driver amplifiers have been listed to drive the LO port of each mixer with low input power.
The parts are priced from; HMC8191 (2.5 to 8.5 GHz) – $54.94; HMC8193 (6 to 26 GHz) – $29.42; HMC8192 (20 to 42 GHz) – $57.40.
