DescriptionNamePin Number
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.
