Silicon platform cuts tuner parts count
StreamCharger from SiGe is a silicon platform that enables the world's lowest power, most integrated downstream tuners for DOCSIS cable telephony equipment, cable modems and digital set-top boxes.
SiGe Semiconductor's new transceiver chipset provides system designers with the full transmit and receive paths, and requires minimal external components.
Featuring industry-leading performance with optimal gain control, low phase noise, and low noise figure, the chipset supports a large bandwidth and transmission range required for simultaneous broadband delivery of high-speed voice, data and video services.
The new transceiver is equipped with multiple baseband interfaces, able to support HD-FDD BPS-IF, HD-FDD IQ and TDD IQ baseband controllers.

Power amp covers both Bluetooth and Wi-Fi
The SE2520L from SiGe Semiconductor is a linear 2.4GHz power amplifier that is fully compliant with both Bluetooth 1.1 and IEEE 802.11b specifications.
This, combined with a wide bandwidth of 3.3-3.8 and 2.3-2.7GHz, allows manufacturers to use a single solution to address worldwide frequencies.
Original equipment manufacturers thus reduce cost of inventory and design resources when bringing new WiMAX-capable products from concept to market.
"Our new WiMAX transceiver leverages SiGe's RF design and process technology expertise to offer customers an optimised solution relative to overall performance and flexibility", said Andrew Parolin, Director of Wireless Data Products, SiGe Semiconductor.
"We are also providing our customers with design and layout support to help them to take WiMAX products based on our devices through the certification process".
SiGe Semiconductor's new transceiver chipset includes four devices: the SE7051 IF transceiver, the SE7351L 3.5GHz RF transceiver, the SE7251L 2.5GHz RF transceiver and the SE7380L switch.
The SE7051L IF transceiver interfaces directly to most commercially available baseband controllers, providing high integration, low noise and high linearity.
The device features dual IF and RF synthesisers as well as a high speed digital VGA delivering 50dB of gain control.
The SE7351L and SE7251L RF transceiver ICs are designed to deliver the high linearity and low phase noise that is ideal for high order modulation schemes.
The new transceivers are equipped with a high-speed receive AGC.
The SE7351L and SE7251L support tuning ranges from 3.3 to 3.8 and 2.3 to 2.7GHz, respectively, and deliver 40dB of gain control.
The SE7380L is a GaAs PHEMT single pole double throw (SPDT) switch ideally suited for transmit and receive switching applications in the 3 to 4GHz band.
The part is designed for low insertion loss and high linearity for maximum dynamic range with complex modulation formats.
The SE7351L and SE7251L are each packaged in a 40-lead QFN package measuring 6 x 6mm, the SE7051L is packaged in a 56-lead QFN package measuring 8 x 8mm, and the SE7380L is packaged in a 6-pin QFN.
