DESCRIPTION
The SA2410 is a GaAs monolithic power amplifier with an integrated T/R switch designed to meet requirements for 802.11 (WLAN). The SA2410 uses an on–chip 4 GHz oscillator to generate the negative bias, thus eliminating the need for a negative supply. It operates from 3V to 5.5V and consumes 125 mA with an output power of 18.5 dB (typ). It is suitable for other 2.45 GHz ISM band applications.
FEATURES
- VCC =3V–5.5V
- No negative bias needed
- ICC =125mA (typ) @ 3.3V
- POUT =18.5 dB(typ) IM3<–30dBc IM5<–50dBc
- Gain=29dB (typ)
- Attenuation range=16dB (typ)
- LQFP–32 package
