The MAX19993 is a dual-channel downconverter designed for diversity receiver applications in the frequency range of 1200MHz to 1700MHz. It offers 6.4dB conversion gain, +27dBm input IP3, 15.4dBm 1dB input compression point, and a noise figure of 9.8dB. The MAX19993 also provides excellent linearity and noise performance, and features integrated double-balanced passive mixer cores, LO buffers, a dual-input LO selectable switch, and a pair of differential IF output amplifiers.
The MAX19993 is a dual‑channel SiGe downconversion mixer designed for 1200 MHz to 1700 MHz RF operation. It offers 6.4 dB typical conversion gain, +27 dBm input IP3, 15.4 dBm 1 dB compression point, and a 9.8 dB typical noise figure. The device integrates two passive mixer cores, LO buffers, a selectable SPDT LO switch, and differential IF amplifiers, all in a 36‑pin TQFN‑EP package.
Typical applications include WCDMA/LTE base stations, wireless local loop, fixed broadband wireless access, private mobile radios, and military systems. The part is pin‑compatible with several Maxim mixer families, allowing reuse of PCB layouts across multiple frequency bands.
