New 2.5G InGaP HBTs from Anadigics (New Devices)
Warren, NJ. Anadigics has introduced two new InGaP HBT power amplifiers for use in multi-mode, multi-band CDMA handsets that support 2.5G applications. The AWT6105 is specifically designed for cellular CDMA, CDMA-1X and AMPS applications in the 824849 MHz range. The AWT6106 targets PCS, MA and CDMA-1X applications operating at 18501910 MHz. Both devices combine all of the required components for full compensation and 50 input/output matching. Both the AWT6105 and AWT6106 are 3.5 V DC devices with 6 mm 6 mm package footprint, 1.6 mm profile and low leakage current. The AWT6105 demonstrates 37% PAE in the CDMA bandwidth and 45% in the AMPS bandwidth, while the AWT6106 provides 35% PAE (see ). www.anadigics.com
