WARREN, N.J. Anadigics Inc. has introduced two radio-frequency ICs for building lighter, smaller multimode, multiband handsets. The AWD-5201S4 driver amplifier and the AWT4502S4 power amplifier offer 3-volt operation, a small footprint and 50-ohm input/output matching, said Barak Maoz, vice president of wireless power amplifier products.
The AWD5101S4 is a dual-band driver amplifier that supports PCS TDMA, cellular TDMA, and AMPS digital and analog protocols. The device features an on-chip bias circuit and requires only fixed voltages for optimal performance.
The AWT4502S4 is a transmit power amplifier designed for PCS TDMA wireless handset applications. It delivers 28.5-dBm minimum output power and is said to feature low quiescent current and good linearity.
Both parts are available in 16-pin single small-outline packages. The AWD5101S4 is priced under $3 and the AWT4502S4 sells for $3.50 in quantities of 10,000.
