MACOM's MA4IQP900H-1291T is a silicon monolithic 850-960 MHz, high barrier, I/Q Modulator/Demodulator. Encapsulated in a low cost, miniature surface mount FQFP-N 6mm Square, 28 lead plastic package the die utilizes MACOM'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 base station applications where small size and high performance is required. Typical applications include upconvertion and downconversion requirements in wireless receivers and transmitters.
