The SME1400B-17 is a passive double-balanced diode-ring
mixer that provides high dynamic range performance in a
RoHS-compliant surface mount package. The mixer is
nominally driven with a LO input power of +17 dBm to
optimize its performance. Other SME models are available
for other LO drive levels.
Typical applications include frequency up/down
conversion, modulation and demodulation for receivers and
transmitters used in 2.5G and 3G GSM/CDMA/W-CDMA
systems.
