The following figure shows the SiW1721B Radio Modem functional block diagram.During the receive process, the radio signal is taken from the single-ended RF input pin that feeds into the low noise amplifier (LNA).The signal from the LNA is directly down-converted to I/Q baseband, filtered with an anti-aliasing filter, and converted to a digital signal with a high resolution analog-to-digital converter.The critical channel filtering is done in the digital domain for stable
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 c.
