AP1098

2.4~2.5 GHz Power Amplifier

2004.07.19 Preliminary

• Ultra LOW Current (see below specs)

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.

• Ultra High Efficiency:

PAE>28% @802.11g linear power

• Gain: 25 dB

Under Vc=3.3V, Vref=3V

* 11g

linear power: 19dBm

current: 85mA

* 11b

linear power: 23dBm

current: 165mA

• Low Idle Current: 25mA
