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 (V
CTR
). 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
