VHF/UHF LNAs for mobile devices

Semiconductor Company of Panasonic Corporation has developed VHF/UHF low-noise amplifiers (LNA) for mobile devices to operate at voltages as low as 1.7 V.

Orthogonal frequency division multiplexing (OFDM) LSIs, that receive signals from an LNA, have adopted the finer processes and have reduced the power supply voltage. This industry trend has eliminated 2.8 V power supplies as the standard power supply within a mobile terminal. Moreover, conventional LNAs have required separate amplifiers specific to each band of VHF and UHF.

Panasonic's new single-chip LNAs can handle both VHF and UHF bands and operate at low voltages, eliminating the need for a 2.8 V power supply. These Panasonic LNAs allow mobile terminals to receive one-segment broadcasts, multimedia broadcasts, which will start in April 2012 in Japan, and an ATSC-M/H service in North America. The LNAs have also enabled mobile terminals to receive signals even in areas subject to weak radio waves, for a longer time.

These Single-chip LNAs support a wide range of VHF and UHF frequencies (40 to 900 MHz).

Samples will be available at the end of March 2011 at a unit price of 100 yen.
