Product Description:
Small 4x4 Package The TQ5638 is a CDMA Rx Receiver designed for KPCS-Band, Dual-Mode operation. The device supports KPCS CDMA and GPS. The IF range is from 80 MHz to 230MHz Full ESD Protection with external tuning. The Low Noise Amplifiers have an adjustable third order intercept Few external components (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 System Advantage they feature excellent linearity and low noise figure. Most compact integrated receiver for KPCS This device is available in a 4X4 mm MLF package with 24 pins. The TQ5638 frontCDMA and A-GPS applications end receiver is capable of meeting all electrical requirements in accordance with the IS-98 IMD requirements met with 2 gain TIA/EIA 98-C Wireless Communication standard. states simplifying calibration procedures
