Microsemi Corporation, a manufacturer of high performance analog and mixed signal integrated circuits and high reliability semiconductors, has announced that it has shipped a total of 100 million units of its Wireless Local Area Network Radio Frequency Power (WLAN RF) Amplifiers.
“Microsemi’s (News - Alert) RF power amplifiers continue to be designed into the world’s leading WLAN platforms by customers and reference design partners who have grown to expect our superior performance and best in class power efficiency,” said Steve Litchfield, executive vice president and general manager of the Analog Mixed Signal Group for Microsemi Corporation. “Our portfolio of RF power amplifiers enables the development of high-performance WLAN solutions that provide extended range, superior reception, and reduced power consumption for various WLAN standards including 802.11a/b/g and 802.11n.”
Microsemi semiconductors, according to the company, manage and control or regulate power, protect against transient voltage spikes and transmit, receive and amplify signals, and Microsemi RF power amplifiers are used in mobile handsets, wireless access points, half mini-cards for notebooks and netbooks, implanted medical products, aeroplanes, satellites, monitors, LCD TVs, automotive and mobile connectivity applications.
Wireless amplifiers for the cellular market segment assume significant importance because in 2008 alone 1.21 billion mobile handsets, including 171 million smartphones, were sold globally, as reported by TMCnet, and this figure brought the total number of mobile phones on this planet to approximately 4 billion.
While selecting a full scale cellular amplifier it is important to keep in mind, as reported by TMCnet, the following guidelines: Bi-directional amplification to significantly boost downlink and uplink signal strength, high downlink receiver sensitivity to enhance clear sound signals, high uplink output power to avoid dropped calls, oscillation detection and shutdown to avoid cellular interference and possible signal chopping, cell site overload protection to avoid garbled communications, purchase only money-back guaranteed products, and the customer must carefully read all the fine print to make sure the guarantee is legitimate.
Don’t forget to check out TMCnet’s White Paper Library, which provides a selection of in-depth information on relevant topics affecting the IP Communications industry. The library offers white papers, case studies and other documents which are free to registered users.
