Freescale introduces world's first multi-stage RFICs optimized for 2.7 and 3.5 GHz WiMAX base station power amplifiers

Freescale Semiconductor has introduced three high power LDMOS Radio Frequency Integrated Circuits (RFICs) that allow designers of RF power amplifiers for WiMAX base stations to reduce costs, form factors and part counts. The devices are engineered to also increase performance and reliability when compared with amplifiers employing discrete RF power transistors.

Devices deliver cost savings enabled by over-molded plastic packages and higher integration

The devices extend Freescale's portfolio of RFICs to the two primary bands utilized by WiMAX throughout the world – 2.7 GHz and 3.5 GHz. They are the first RFICs available in over-molded plastic packages to operate at these frequencies, enabling them to leverage cost and mechanical stability advantages. They are also the first such devices to integrate multiple gain stages into a single over-molded plastic packaged device, thereby reducing cost, size and complexity.

The MW7IC2725N and MW7IC2750N RFICs operate from 2.3 to 2.7 GHz, and the MW7IC3825N operates from 3.4 to 3.6 GHz. All three devices use Freescale's seventh-generation high-voltage (HV7) LDMOS process technology, which has been deployed worldwide in discrete field-effect transistors (FETs), as well as in RFICs for wireless applications operating at 900 MHz and 2 GHz.
