The device supports KPCS CDMA and GPS. The IF range is from 80 MHz to 230MHz with external tuning. The Low Noise Amplifiers have an adjustable third order intercept (IP3) to minimize inter-modulation and cross-modulation effects. The mixers are designed for differential IF outputs (single-ended or differential IF for GPS modes), and they feature excellent linearity and low noise figure. This device is available in a 4X4 mm MLF package with 24 pins. The TQ5638 frontend receiver is capable of meeting all electrical requirements in accordance with the TIA/EIA 98-C Wireless Communication standard.
