Configurable components for cellular and WLAN

10 June 2009 Telecoms, Datacoms, Wireless, IoT

By integrating multiple common radio frequency (RF) functions into highly integrated, small packages, the integrated configurable components enable designers to develop radio systems that operate over a wide dynamic range and across a broad range of frequencies and channel bandwidths.

The RF2057 provides designers of cellular repeaters an improved level of integration within the performance parameters required to meet the W-CDMA/PCS specifications for pico and mini repeaters. It includes all functions required for frequency down-conversion and up-conversion, a fractional-N phase locked loop (PLL) synthesiser capable of tuning accuracy of approximately 1 Hz, a wideband monolithic voltage controlled oscillator (VCO) with a tuning range of 1900 MHz to 2400 MHz, local oscillator (LO) drivers and two double-balanced wideband mixers with a minimum IIP3 of +18 dBm.

The RF2059 provides designers of WLAN systems a simplified solution for converting RF signals between the 2,4 GHz and 900 MHz ISM bands. The device is placed between the WLAN chipset and the RF front end, and all functionality necessary for frequency conversion is integrated on-chip.

The RF2059 contains a PLL synthesiser, a VCO capable of meeting WLAN linearity and accuracy requirements, and two double-balanced mixers for receive and transmit paths. By integrating the synthesiser, VCOs and mixers on-chip, combined with the buffer circuits usually required to implement the functions discretely, the device delivers significant circuit board space savings and simplicity of implementation, versus typical discrete implementations, with negligible signal degradation (typically less than 0,8% RMS). The RF2059 is programmed and controlled through a simple 3-wire interface and housed in a compact 5 x 5 mm package. The transverter can also be used in certain cellular repeater systems.
