Transmit Integrated Circuit for Deal Band Cellular Phones
The MAX2361 includes I/Q-modulator, IF VGA, dual IF VCOs, dual synthesizers, upconverters, RF VGA, and 3 RF power amplifier drivers. The drivers' high +11 dBm linear output power allows driving the power amplifiers directly. This typically eliminates two SAW filters and two external PA drivers. The wide frequency range and dual IF ports make the device ideal for a variety of different dual-band and dual-mode radio architectures.
The MAX2363 suits single-band PCS and W-CDMA applications, whereas the MAX2365 suits single-band, dual-mode cellular-band applications.
The MAX2361/MAX2363/MAX2365 are packaged in a 48-pin leadless QFN that measures 7 mm × 7 mm.
