rf micro devices ? offers the SIW1722 ? 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 ? 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 fr equencies. the SIW1722 radio modem uses direct conversion (zero-if) architecture. this allows digital filtering for excellent inter fer ence r ejection as compar ed to low if solutions, which have lower rejection due to analog matching limitations. the r eceiver featur es high sensitivity due to a low noise rf design combined with an advanced modem design. a fast har dwar e agc enables full discover y 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. bluetooth ? technology solutions SIW1722 SIW1722 block diagram features on-chip 50 ohm rf match network with no exter nal impedance matching components fully compliant 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 components highly sensitive receiver with excellent interference r ejection per for mance hardware agc dynamically adjusts receiver performance in changing environments low out-of-band spurious emissions prevents inter fer ence with mobile phone fr equencies class 2 and 3 transmit output power up to +4 dbm output power control loop for accurate power control on-chip voltage r egulation simplifies voltage input requirement low power consumption in active and standby modes 90 0 adc adc pll synthesizer 90 0 dac dac serial bus interface (sbi) gfsk modem voltage regulator and power distribution pll control clock distribution register file system control internal 50-ohm match network power control lna cdma chipset with integrated bluetooth ? baseband modem i/f & data control i/f
