Down Converter with LO, IF Amplifiers
The TriQuint CMY213 is a general purpose down-converter device designed for receiver applications such as cellular and PCS mobile phones, ISM bands, GPS receivers, L-band satellite terminals, WLAN and pagers. It is particularly suited for CDMA receiver applications due to its excellent intermodulation characteristics and its high conversion gain.
The device combines an ultra-linear mixer with LO driver and a single stage IF amplifier in a very small SCT598 package. The mixer section of CMY213 combines low conversion losses and excellent intermodulation characteristics with low requirements of LO and DC power. The internal level controlled LO buffer enables a good performance over a wide LO level range. The input and output matching of the IF amplifier can be adapted externally within a frequency range from 45 to 250 MHz.
