Fairchild Semiconductor has developed a high performance linear RF Power Amplifier Module (PAM) for CDMA and CDMA2000-1X personal communications system (PCS) applications.

Housed in a compact 4-by-4mm package, the RMPA1959 features single positive-supply operation, low power and shutdown modes, and 39 percent CDMA efficiency at 28dBm average output power.

"With the introduction of the RMPA1959, Fairchild offers a complete family of 4-by-4mm RF power amplifiers for CDMA/CDMA2000-1X, for U.S. PCS, Korean band, cellular band and WCDMA devices," said Russ Wagner, GM of Fairchild's RF power products group. "Manufacturers now have a high-performance, cost-effective solution for adapting handset designs to meet worldwide market requirements."

According to the company, the linear power amplifier's low power consumption and excellent linearity are the result of its proprietary InGaP Heterojunction Bipolar Transistor (HBT) technology. The two-stage device internally matches both the input and output to 50 ohms to minimize the use of external components.

The linear power amp is priced at $1.07 each in 100,000-unit orders.
