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.
This device is available in a 4X4 mm MLF package with 24 pins. The TQ5139 front-
end receiver is capable of meeting all electrical requirements in accordance with the
TIA/EIA 98-C Wireless Communication standard.
