Cutting GSM Costs Through Power Control PA IntegrationCutting GSM Costs Through Power Control/PA IntegrationBy combining power control and power amplification functionality in thesame die, engineers can bring higher levels of integration to GSM handsettransmit paths without sacrificing radio performance.Advancing GSM architectures many not seem like a sexy topic in an age where2.5G and 3G technologies are the talk of the town. However, the reality isthat like AMPS in the past GSM is becoming a base technology that allfuture mobile devices must support to be successful.To serve as a base technology, GSM must move from a high-price wirelessoption to a low-cost radio architecture that can be embedded in a host ofmobile designs. One way to cut price is by bringing higher levels ofintegration in the tr……
