Vga I/q Demodulator Rx Asic For Portable Phone Applications Solutions Inc.

The CX74005 Application-Specific Integrated Circuit (ASIC) is a Variable Gain Amplifier (VGA) and I/Q Demodulator intended for use in Code Division Multiple Access (CDMA) portable phones in both cellular and Personal Communications System (PCS) bands. As a trimode IC, it CAN be used in CDMA mode or Advanced Mobile Phone System (AMPS) mode. The device incorporates a VGA and the In-Phase and Quadrature (I/Q) Demodulator stages. The intermediate frequencies (IF) are combined through separate Buffers at the input of the VGA depending on the selected mode. The VGA has a gain control range greater than 90 dB. There are two Very High Frequency (VHF) Oscillators that operate with external tank circuits. They provide signals to the Local Oscillator (LO) for the I/Q Demodulator in the cellular and PCS bands. The noise figure, gain, and third order Input Intercept Point (IIP3) of the CX74005 are optimized to meet the system requirements for AMPS and CDMA modes as per TIA/EIA-98-B, ANSI J-STD-018 (PCS), CDMA2000. Employing silicon bipolar technology, the ASIC is designed for high performance, a high level of integration and low cost. By Skyworks Solutions, Inc.
