Product Description:

The TQ5139 is a CDMA Rx Receiver designed for Cell-band, Dual-mode operation. The device supports Cell CDMA and A-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 outputs for GPS modes), and they feature excellent linearity and low noise figure.
