CGB 240B Datasheet 2-Stage Bluetooth & WLAN InGaP HBT Power Amplifier 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 IEEE802.11b-modulated 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.

A the discrete matching concept shown in figure 10 uses no transmission lines but only discrete components to provide device matching. The use of a discrete matching concept saves PCB space an makes the design more tolerant towards variations of the PCB's r , but will lead to a lower output power (typ. 0.3 dB lower) and higher BOM cost.
