Freescale Bolsters RFmobile Radio Position With 4W Airfast Device

AirfastAFT05MS004N combines high performance with superior gain, efficiency and bandwidth in a SOT-89 plastic package

(International Microwave Symposium) – Freescale Semiconductor is augmenting its flagship Airfast RF power solutions portfolio with the addition of the AFT05MS004N 4W RFpower device for handheld and mobile radio applications. The device delivers outstanding low power operation and extends the company’s support of mobile radio power levels to the 4W - 75W range.

Notable performance features include high gain to reduce the number of stages, energy efficiency improvements that reduce heat sink form factors, and exceptional ruggedness at a> 65:1 VSWR survivability rating for continuous reliable operation in extreme environments. The AFT05MS004Nis characterized at frequencies from 136 to 941 MHz and can operate as low as 2 MHz. It is available in a cost-effective SOT-89 plastic package and is part of Freescale’s product longevity program.

The AFT05MS004N is ideal for a wide range of applications including public safety radios, professional mobile radios, electric metering, M2M communications and industrial drivers.

Airfast AFT05MS004N Features

  • Small form factor - highly versatile device that meets the needs of multiple applications
  • Industry’s best ruggedness - survives > 65:1 VSWR with simultaneous over voltage and 3 dB overdrive
  • High gainat >4W output power- eliminates stages, there by reducing system cost
  • High efficiency - simplifies cooling and enables smaller end products, allows use of smaller heat sinks and housings
  • Broadband width capability - enables full performance across each mobile radio band

The AFT05MS004N is supported by a comprehensive set of broadband designs and fixtures available for reference, as well as global and regional applications support from Freescale.
