SiGe Semiconductor announces silicon-based CDMA power amplifiers. The amplifiers, SE5103L, SE5106L, and SE5107L, feature integration with on-chip digital or analog bias control, as well as an integrated power detector,2.8 V regulator, all matching and harmonic tuning. The RangeCharger amps feature linearity of <㫊 dBc at a peak output power of +28 dBm, and a power added efficiency (PAE) exceeding 41%. Additional features include ESD up to 2 kV, and load mismatch protection circuitry. These features ensure performance under VSWR conditions of 10:1, at all phases and VCC_MAX. These products support drop-in replacement and are single-band, two-stage amps suitable for IS-95 and CDMA cellular handsets operating in the 824 to 849 MHz cellular band.
