SIW1722 Datasheet | RF Micro Devices

Features   On-chip 50 Ohm RF match network with no external impedance matching ponents munications and is based on 0.18 µm CMOS technology. The highly integrated transceiver was specifically designed to meet the rigorous RF performance required for integrating Bluetooth technology into CDMA-based mobile phone applications. The Si W1722 radio modem bines a 2.4 GHz radio transceiver and Gaussian Frequency Shift Keying (GFSK) modem with digital control functions. The IC also incorporates analog and digital voltage regulators, a power-on-reset (POR) circuit and a reference Phase Lock Loop (PLL) to enable multiple input frequencies. The Si W1722 radio modem uses direct conversion (zero-IF) architecture. This allows digital filtering for excellent interference rejection as pared to low IF solutions, which have lower rejection due to analog matching limitations. The receiver features high sensitivity due to a low noise RF design bined with an advanced modem design. A fast hardware AGC enables full discovery of any device within the dynamic range of the receiver, solving near-far issues. The transmitter can maintain a stable output power level up to +4 d Bm for class 2 operation, which in bination with the excellent receiver performance, ensures the maximum possible range at the lowest system cost.   Fully pliant with Bluetooth specification 1.2   Digital interface to CDMA chipsets with an integrated Bluetooth baseband   Supports multiple external reference clocks or crystal frequencies with on-chip reference PLL   Direct-conversion architecture with no external channel filter or VCO resonator ponents   Highly sensitive receiver with excellent interference rejection performance   Hardware AGC dynamically adjusts receiver performance in changing environments   Low out-of-band spurious emissions prevents interference with mobile phone frequencies   Class 2 and 3 transmit output power up to +4 d Bm - output power control loop for accurate power control   On-chip voltage...
