T0353

The T0353 is a CDMA front-end receiver RFIC designed for Tri-band, quad-mode operation. The T0353 supports AMPS, Cell CDMA, PCS CDMA, and A-GPS operation.The IF range is from 80 MHz to 230 MHz with external tuning. The low-noise amplifiers have an adjustable third order intercept point (IP3) to minimize inter-modulation and cross-modulation effects. The mixers are designed for differential IF outputs (single-ended or differential IF outputs for AMPS and GPS modes), and they feature excellent linearity and low-noise figure.

The T0353 also integrates a divide-by-2 frequency divider to allow the use of only one VCO module for both CDMA bands. However, it also has the option of connecting the LO directly to the cellular mixer LO input. This device is available in a 5 mm x 5 mm MLF package with 32 pins. The T0353 front-end receiver is capable of meeting all electrical requirements in accordance with the TIA/EIA 98-C wireless communication standard.
