The UAP106/232 Universal Access Point (UAP) femtocell from Global Wireless Technologies will use the single-chip, multi-band, multi-standard LMS6002DFN RF transceiver from Lime Microsystems. The UAP106/232, which is a configurable platform for femtocells supporting WCDMA and CDMA2000 standards, is software-upgradeable to support 4G Long-Term Evolution (LTE).

The platform uses the LMS6002DFN in the full range of frequencies between 700 MHz and 3.8 GHz with multiple bandwidths of up to 20 MHz. Global Wireless Technologies has validated the transceiver by performing data and voice calls in WCDMA band 1, 2, and 5. According to the company, the UAP106/232 gives mobile providers a high-capacity, consumer-enterprise cellular access point in an unobtrusive form factor.

With peak data rates from 7.2/3.1 Mbits/s and voice channel capacity of up to 32 users, the UAP is designed to deliver top performance, flexibility, and ease of deployment and use. Mobile users sending or receiving voice or data calls on their existing mobile terminals within range of the UAP should get improved coverage.

The LMS6002DFN can be digitally configured to operate in the full range of frequency bands from 375 MHz to 4 GHz with 16 user-selectable bandwidths of up to 28 MHz (see the figure). As a result, it can transmit and receive data across all WCDMA and CDMA bands, as well as those used or planned for WiMAX and LTE. This removes the need for individual transceiver chips for each of the different bands. It also enables small cell basestations to be reconfigured rapidly and simply. The resulting reduction in bill of materials reduces costs and inventory for OEMs.

The UAP106/232 Universal Access Point femtocell from Global Wireless Technologies will use the LMS6002DFN RF transceiver from Lime Microsystems to provide multi-band, multi-standard performance.

The transceiver’s high-performance dual 12-bit analog-to-digital converter (ADC) and digital-to-analog converter (DAC) blocks provide the necessary multiplexed parallel interface to all currently available baseband ICs on the market for femtocell applications. Housed in a 9- by 9-mm, 116-pin depopulated very thin quad flat-pack no-leads (DQFN) package, the LMS6002DFN is available alongside an evaluation platform and reference design.
