The SiW1711TM Radio Modem is Silicon Wave's third-generation radio modem for Bluetooth wireless communications and is based on 0.18m CMOS technology. This highly integrated transceiver was specifically designed to meet the rigorous RF performance required for integrating Bluetooth into mobile phone applications. The SiW1711 Radio Modem combines a 2.4GHz radio transceiver and Gaussian Frequency Shift Keying (GFSK) modem with digital control functions. The IC also incorporates analog and digital voltage regulators, a reference Phase Lock Loop (PLL) to enable multiple input frequencies, and a power-on-reset (POR) circuit. The SiW1711 Radio Modem uses direct conversion (zero-IF) architecture. This allows digital filtering for excellent interference rejection as compared to low IF solutions, and also results in fewer spurious responses. The receiver has excellent sensitivity due to a low noise RF design combined with an advanced modem design. A fast hardware AGC enables full discovery of any device within the dynamic range of the receiver (solves near-far issues). The transmitter can maintain a stable output power level up to +4dBm for class 2 operation, which in combination with the excellent receiver performance ensures the maximum possible range at the lowest system cost. The device is available in a 32-pin QFN package with 5 x 5 x 1 mm dimensions. Known good die with bumps is also available. Operating temperature range is guaranteed from -40C to +85C with available extended high temperature range to 105C.
