TriQuint Semiconductor Inc. has introduced its new dual-band UMTS power amplifier module (PAM) in a small form factor4-by-4-by-1.1mm.

The TQM7M60001 module is designed to support cost-effective GSM/EDGE/UMTS (HSDPA) compressed mode phone architectures with only one antenna. According to the company, the TQM7M6001 is a breakthrough because its biasing circuit is optimized for low idle current consumption (below 30mA), which results in increased handset talk time in UMTS mode.

The product's output power (27.5dBm min.) offers ample margin for front-end losses, enabling cost-effective GSM/ EDGE/UMTS multi-mode phone designs utilizing compressed-mode seamless hand-over to the GSM/EDGE global network. In addition, its linearity (7dB margin to ETSI-requirements for UMTS) offers sufficient margin for applying additional transmit channels for large-scale data transmission rates, enabling next generation 3G phones for HSDPA (high speed download packet access).

"This market-leading UMTS dual-band PAM offers outstanding performance enabling phone designers to meet UMTS system specifications in IMT2100 and PCS frequency bands over bias and temperature range, even for next generation 3G phones supporting upcoming standards such as compressed-mode hand-over or HSDPA," shared Juergen Hartmann, UMTS product marketing manager.

The press release said that TriQuint's low cost design architecture allows the company to offer the TQM7M6001 at very competitive prices. Its 50-ohm input and output impedance, plus its outstanding suppression of unwanted harmonic signals and receive band noise save customers the need for external matching or suppression circuits and guarantees compliance with all of today's available front-end components. This combination of high-level integration and reduced part count cuts costs while reducing manufacturers' BoM, the company added.

An advance data sheet for the TQM7M6001 is available online.
