HIGHLY INTEGRATED TRANSMIT IC FOR DUAL-BAND CELLULAR PHONES
SUNNYVALE, CA-December 7, 2001-Maxim Integrated Products introduces the MAX2361/MAX2363/MAX2365 baseband-to-PA complete dual-band cellular phone transmit ICs. They are designed for dual-band, dual-mode, and single-mode N-CDMA, TDMA, GAIT, and W-CDMA cellular phones. A key feature of the MAX2361 series is high integration level, which dramatically reduces component count and size.
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 +11dBm 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 only 7mm x 7mm. Prices start at $5.43 (1000-up, FOB USA).
