Description and Applications
M/A-COM's MA4IQP900M-1291T is a silicon
monolithic
850-960 MHz, medium barrier, I/Q
Modulator/Demodulator. Encapsulated in a low cost,
miniature surface mount FQFP-N 6mm Square, 28
lead plastic package the die utilizes M/A-COM’s
unique HMIC silicon/glass process. This process
enables the realization of low loss passive elements
and efficient diode technology which in turn provides
excellent harmonic suppression. In addition, the
incorporated monolithic design techniques provide
unparalleled amplitude and phase imbalance
performance during demodulation thus adding to the
units overall versatility.
These modulators/demodulators are well suited for
GSM and CDMA Cellular basestation applications
where small size and high performance are required.
Typical applications include upconvertion and
downconvertion requirements in wireless receivers
and transmitters.
