October 20, 2004 Geneva, Switzerland STMicroelectronics introduced a linear power amplifier for use in wireless LAN applications meeting the IEEE802.11b/g standards. It is designed for use in notebooks, PCs, PDAs and other mobile products.
A three-stage linear power amplifier optimized for 2.4GHz, the device includes a bias network to improve linearity, power-down and quiescent current regulation. Featuring 32dB of power gain and +19dBm of linear output power, the part has an error vector magnitude of just 2% under 802.11g modulation at 54Mbit/s. Current consumption is 125mA at 19dBm output and 60mA when quiescent.
The part includes a linear analog control for DC current and output management and an average channel power detector that does not need an external integrator, op amp or coupler, reducing the bill of materials and board real estate.
The STB7720L is offered in a QFN16 3 x 3mm leadless package and is priced at US$1.30 in quantities of 10,000 units.
