Freescale Achieves RF Power Breakthrough for GSM Wireless Markets.Freescale RFICs Are First to Deliver 100-Watt RF Output Power for 900 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and 1800 MHz GSM and EDGE Base Stations BARCELONA, Spain -- The industry's first two-stage RF Integrated Circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (RFICs) capable of delivering the 100-watt (W) RF output power required for GSM and EDGE network base stations debuted today from Freescale Semiconductor Freescale Semiconductor, Inc. is an American semiconductor manufacturer. It was created by the divestiture of the Semiconductor Products Sector of Motorola in 2004. Freescale focuses their integrated circuit products on the automotive, embedded and communications markets. at the 3GSM World Congress. The devices are the highest power two-stage RFICs to be offered commercially.

The advantages are significant for the GSM and EDGE market. Historically, the output power of two-stage RFICs has been limited to less than 30 W, relegating their utility to driver and pre-driver stages. Previous designs required a separate high power transistor to achieve the 50 dB of gain and the 100 W of output power typically required for GSM EDGE transmitters. Now, only a GPA and a single RFIC RFIC Radio Frequency Integrated Circuit RFIC Radio Frequency Interface Chip combine to meet this requirement. "These 100 W RFICs are a breakthrough in RF power technology for the wireless marketplace," said Gavin P. Woods, vice president and general manager of Freescale Semiconductor's RF Division. "They are the highest power two-stage RFICs ever commercially offered and they are housed in over-molded plastic rather than air cavity packages. Either of these advancements alone would be significant, but together they represent a significant step forward for the industry." Technical specifications: the MWE6IC9100N The MWE6IC9100N is designed for both the 869 to 894 MHz cellular and 920 to 960 MHz GSM bands. For GSM operation, the device is designed to deliver CW output power of at least 100 W at 1-dB gain compression (P1dB) in 28 V Class AB bias conditions. Gain is 33.5 dB and power added efficiency is in excess of 52 percent over the intended operating range. Under a 28 V drain bias and 50 W average output power in an EDGE application, the MWE6IC9100N addresses the stringent linearity requirements with spectral regrowth Re`growth´ n. 1.

Technical specifications: MW7IC18100N The MW7IC18100N covers the 1805 to 1880 MHz and 1930 to 1990 MHz bands. It is designed to deliver P1dB RF output power of 100 W CW with 30 dB of gain and power added efficiency of 48 percent over the intended operating range when running in a GSM environment at 28 V. EDGE performance includes average power of 40 W, spectral regrowth of -63 dBc (400 kHz offset) and -80 dBc (600 kHz offset), with EVM of 1.5 percent rms. Housed in cost-effective over-molded plastic packaging, both RFICs are internally-matched and exhibit outstanding ruggedness. They have integral ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine.

They also include an integral quiescent current thermal tracking device that provides effective temperature compensation to keep current constant within five percent over a 115[deg]C operating temperature range for all amplifier stages. The RFICs help simplify power amplifier system designs by incorporating an automatic biasing function, which allows designers to set amplifier biases with minimal external circuitry. Additionally, the devices automatically compensate to set the desired drain quiescent current with a minimum amount of external control circuitry required. Availability The MWE6IC9100N is in full production and available now. The MW7IC18100N is sampling now with full production planned for March 2007. Validated RF models and full lineup demo boards using MMG3005N are available now for both products.
