TriQuint broadens HBT PA portfolio (New Devices)

Hillsboro, OR. Two new PAs have been introduced for cellular handsets employing the TDMA standard. TriQuint s new GaAs HBT-based TQ7125 and TQ7625 chips provide tri-mode TDMA (IS-136/54 standard) operation, resulting in coverage in more geographic markets. Operating from a single 2.75 V supply, these new devices also eliminate voltage regulators from the phone, lowering costs and reducing board space. The TQ7125 is an analog and TDMA PA with an output power of 29.5 dBm and PAE of 47%, in addition to an adjacent channel performance figure of better than 29 dBc. The TQ7625 chip is a TDMA PCS PA with an output power of 28.0 dBm and typical efficiency of 40%. Both devices are available in 3 3 mm leadless packages. TriQuint has further broadened its product portfolio with the announcement of a CDMA power amplifier based on SiGe, the first device to spring from a joint development with Atmel (see page 25). The TQ7135 is a 3 V, two-stage HBT for use with IS-95/98 and AMPS compliant phones. The efficiency is 40% and gain 28 dB. Two power modes (94 and 72 mA) are designed to minimize quiescent current in the device, which features a 4 mm 4 mm footprint.
