2-Stage Bluetooth InGaP HBT Power Amplifier
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-
For WLAN applications (IEEE802.11b) or appli-
cations serving both WLAN and Bluetooth, we
recommend to use the CGB240B device.
