AP1098

www.DataSheet4U.com AP1098 2.4~2.5 GHz Power Amplifier 2004.07.19 Preliminary The AP1098 is a linear, low current power amplifier in ISM band utilizing InGaP /GaAs HBT process. It features a LOW current of 85mA, small signal gain of 25 dB, linear power of 19dBm and PAE of 28% for 802.11g under 3.3V. It can also be adjusted to smaller current(~60mA) with lower linear power (~16dBm). The AP1098 is housed in a 3 x 3 (mm), 16-pin, and QFN leadless package. The AP1098 is suitable to be used in portable, low current 802.11b and 802.11g WLAN applications.
