Our wireless communications ICs enable reliable and efficient data communications. Focusing on RF signal amplification and processing, our high-performance wireless products support cellular infrastructure designs, including base stations and microwave point-to-point systems.
Digital Predistortion and PA Linearization
Our RF power linearizer (RFPAL) ICs feature a programmable analog signal processing architecture that effectively combines digital programmability with the simplicity, small size, and low power consumption of analog circuits. The benefit provided by this architecture is a pre-distortion linearization solution with very low power consumption, wide bandwidth performance, and a compact system footprint.
Femtocell Base Stations
A femtocell base station connects cell phone voice and data to the cell phone network, but it serves a smaller area, typically a home or office. A femto base station benefits the service provider because it offloads cell tower traffic. Subscribers benefit from superior signal strength, due to the proximity of the unit, especially where a cellular signal is weak or not available. Connection to the cell phone network is provided by VoIP over the Internet.
Our highly integrated single-chip femtocell transceiver family covers WCDMA bands 1-6 and 8-10, and cdma2000® band class 0, 1, and 10.
225MHz to 3800MHz RF Power Amplifier LinearizerSC1894
The SC1894 is a fully adaptive, RFin/RFout predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols.
250MHz to 12.4GHz, High-Performance, Fractional/Integer-N PLLMAX2880
Combined with an external reference oscillator, loop filter, and VCO, the device forms an ultra-low noise and low-spur frequency synthesizer capable of accepting RF input frequencies of up to 12.4GHz.
WCDMA Femtocell Transceiver with GSM MonitoringMAX2550
This device is a complete single-chip RF-to-bits and bits-to-RF radio transceiver. This device is in compliance with the 3GPP TS25.104 femtocell standard for Band I, V, and VIII. It's equipped with multiple receive inputs and transmit outputs for low band, high band, and macro-cell monitoring.
Our wireless communication solutions provide additional information on designing wireless infrastructure products, including examples and block diagrams of typical designs.
