Triquint Semiconductor Debuts TQM7136 Power Amplifer

Triquint Semiconductor (Hillsboro, OR) announced the TQM7136 HBT power amplifier module, which is targeted at the fast-growing cellular phone market. The amplifier exhibits high RF performance, which is enabled by a SiGe semiconductor process.

The power amplifier module maximizes mobile phone talk time by allowing the phone designer to vary the module's power setting as the phone operates in the CDMA network. This module allows rapid development of handset platforms because it requires few external components and it incorporates a CMOS-compatible logic interface. The CMOS interface allows the TQM7136 to be controlled directly with low-voltage CMOS microprocessors without the need for additional circuitry.

Features include 35-percent efficiency, three quiescent current states (25mA, 65mA and 111mA) and -49dBc linearity. The module has an internally matched input and output. It occupies a 6mm x 6mm footprint (eight-pin module) and requires minimal external circuitry. It also comes with full ESD protection.

In 100,000-piece quantities, the TQM7136 is priced at $2.50.
