The CGB240 GaAs Power Amplifier MMIC has been especially developed for wireless applications in the 2.4 - 2.5 GHz ISM band (e.g. Bluetooth class 1). Its high power added efficiency and single positive sup-ply operation makes the device ideally suited to handheld applications. The device delivers 23 dBm output power at a supply voltage of 3.2 V, with an overall PAE of 50%. The output power can be ad-justed using an analog control voltage (VCTR). Simple external input-, interstage-, and output matching cir-cuits are used to adapt to the different requirements of linearity and harmonic suppression in various ap-plications.
For WLAN applications (IEEE802.11b) or appli-cations serving both WLAN and Bluetooth, we recommend to use the CGB240B device.

CGB240B General Description
The CGB240B GaAs power amplifier MMIC has been especially developed for wireless LAN applications in the 2.4 - 2.5 GHz ISM band, compliant with IEEE 802.11b standards. The chip is also fully compliant with Bluetooth class 1 applications and thus can be used in dual-mode (Bluetooth/WLAN) applications, too.
While providing an effective channel power of 22dBm, the ACPR is better than -33dB relative to the sinx/x spectral peak of an IEEE802.11bmodulated TX signal. Each CGB240B chip is individually tested for IP3, resulting in guaranteed ACPR performance.
In a Bluetooth class 1 system, the CGB240B's high power added efficiency (up to 50%) and single positive supply operation makes the device ideally suited for handheld applications. The CGB240B delivers 23 dBm output power at a supply voltage of 3.2 V, with an overall PAE of 50% in saturated mode. The output power can be adjusted using an analog control voltage (VCTR). Simple external input-, interstage-, and output matching circuits are used to adapt to the different requirements of linearity and harmonic suppression in various applications2-stage InGaP HBT power amplifier for WLAN and Bluetooth applications.
