Power amplifier for 1,9 to 2,5 GHz wireless applications

22 March 2006 Power Electronics / Power Management

Toshiba Electronics Europe's new medium power SiGe bipolar complementary metal oxide semiconductor (BiCMOS) power amplifier, the TA4401CT, is well suited for use in 1,9 GHz to 2,5 GHz band wireless applications including wireless LAN (WLAN), personal handy system (PHS) and Bluetooth (BT).

The demand for high performance, low cost radio frequency (RF) amplifiers is increasing in commercial wireless applications. Applications such as WLAN, PHS and BT are experiencing constant pressure to reduce price while maintaining or improving performance. Toshiba says it developed the TA4401CT to meet these challenges - the first in an expected family of SiGe PAs.

The TA4401CT is designed with three cascaded RF stages optimised for linearity, efficiency and low-power consumption. It is specifically applicable for use in regulated IEEE802.11b/g WLAN systems, delivering 18 dBm/mW of average output power with 27,5 dB of gain and 3% of error vector magnitude performance, while consuming just 125 mA of current at 3,3 V supply.

The TA4401CT comes in a low profile Pb-free 16-pin CSP.
