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 supply 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 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 applications. For WLAN applications (IEEE802.11b) or applications serving both WLAN and Bluetooth, we recommend to use the CGB240B device.
