Product profile 1.
1 General description The BGY288 is a power amplifier module in a SOT775 surface mounted package with a plastic cap.
In the module, a mix of state of the art technologies as InGaP, Si-Bicmos and Si passive integration are used to combine high performance with a small size.
The module comprises two functional sections, one for low-band (GSM850/EGSM900) and one for high-band (DCS1800/PCS1900) with internal power detection, power control loop, input and output matching; see Figure 2.
The power control circuit ensures a stable RF power output which is set by the voltage level on pin PC.
The power control circuit is stabilized to compensate for variations in supply voltage, input power and temperature, and has a control range fully compliant with European Telecommunication Standards Institute (ETSI) time mask and power spectrum requirements.
