The SiW1711 Radio Modem is Silicon Wave's third-generation radio modem for
Bluetooth wireless communications and is based on 0.18μm CMOS technology. This
highly integrated transceiver was specifically designed to meet the rigorous RF perfor-
mance required for integrating Bluetooth into mobile phone applications.
The SiW1711 Radio Modem combines a 2.4GHz radio transceiver and Gaussian Fre-
quency Shift Keying (GFSK) modem with digital control functions. The IC also incorpo-
rates 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
-40°C to +85°C with available extended high temperature range to 105°C.
Single chip IC with 2.4 GHz
transceiver and GFSK modem with
digital interface to external baseband
processor.
Fully compliant with Bluetooth
specification 1.1 and 1.2.
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.
Single-ended RX/TX pins reduce
system BOM cost by eliminating a
balun. On-chip RX/TX switching
eliminates external RX/TX switch.
Typical -85 dBm receiver sensitivity
with excellent interference rejection
performance.
Class 2 and 3 transmit output power
up to +4 dBm with output power
control loop for accurate power
control.
Hardware AGC dynamically adjusts
receiver performance in changing
environments.
Low out-of-band spurious emissions
prevents interference with mobile
phone frequencies.
Option for Class 1 designs with
RX/TX switch control and multiple
modes of gain control.
On-chip voltage regulation simplifies
voltage input requirement. Regulator
bypass mode enables use of external
regulator.
1.8 Volt analog and digital core
voltages; 1.63 Volt to 3.63 Volt
external I/O interface voltage.
Low power consumption in active and
standby modes.
