Power amplifier module boosts handset
talk time
The TQM7M6001 is a UMTS power-amplifier module that features an innovative biasing circuit optimised for low idle current consumption, resulting in increased handset talk time.
New from Link Microtek, the exclusive representative for TriQuint Semiconductor in the UK and Ireland, is the TQM7M6001, a UMTS power-amplifier module (PAM) that features an innovative biasing circuit optimised for low idle current consumption, resulting in increased handset talk time Housed in a compact 4.0 x 4.0 x 1.1mm LGA package, the new PAM is designed to support both 3G technology (WCDMA or HSDPA) and GSM/Edge with only one antenna

Microwave components on short lead times
Link Microtek has produced a new shortform brochure providing an overview of the wide range of Narda microwave components now available from stock in the UK and continental Europe.
The device is fabricated using TriQuint's high-reliability InGaP HBT process.
The TQM7M6001's minimum output power of 27.5dBm offers ample margin for front-end losses, thus enabling the development of cost-effective multimode phones that use compressed-mode seamless hand-over between GSM/Edge and UMTS networks.
The 50ohm input and output impedance of the new module, together with its outstanding suppression of unwanted harmonic signals and receive-band noise, eliminates the need for external matching or suppression circuits and guarantees compliance with all of today's available front-end components, such as filters, duplexers and antenna switch modules.
Furthermore, the linearity of the TQM7M6001 is 7dB above ETSI requirements for UMTS, providing sufficient margin for the large-scale data transmission rates associated with the emerging HSDPA (high-speed downlink packet access) technology.
This new PAM exemplifies the type of innovative engineering that TriQuint relies on to set new standards in highly integrated RF front-end system architecture while simultaneously offering the best RF performance at the lowest size and cost targets.
