UltimateBlue™
Radio Modem

The SiW1722™ UltimateBlue™ radio modem is a third-
generation radio modem for Bluetooth® wireless com-
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 SiW1722 radio modem combines 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 SiW1722 radio modem uses direct conversion (zero-IF)
architecture. This allows digital filtering for excellent
interference rejection as compared 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
combined 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 dBm for
class 2 operation, which in combination with the excellent
receiver performance, ensures the maximum possible range at
the lowest system cost.
