SIW1721B

SiW1721B www.DataSheet4U.com 0 Features Integrated RF transceiver and modem for Bluetooth wireless technology. Manufactured using low-power 0.18-micron CMOS process technology. Digital baseband interface connects directly to an integrated Bluetooth controller. Direct conversion RF architecture improves receiver-blocking performance. Low out-of-band spurious emissions minimize interference with mobile phone operations. Hardware AGC dynamically adjusts receiver performance in changing environments. 50 Ω RF I/O does not need additional external impedance matching components. On-chip voltage regulation simplifies system design. -88 dBm receiver sensitivity and +2 dBm transmitter power typical performance specifications. Bluetooth Specification V2.0 qualified. Complies with Bluetooth specifications V1.1, V1.2 and V2.0.
