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.
