Skywork's SKY74073 Single Package Radio (SPR) combines the radio circuitry required for GSM/GPRS 900/1800 handsets into a single compact package. The SPR solution combines a transceiver, PA and associated controller, two SAW filters, and a switchplexer module in a 40-pin, 13 × 13 mm laminate multi-chip module package. The transceiver's direct conversion architecture eliminates IF conversion steps while reducing the number of components required to support multi-band GSM/GPRS handsets and agile channel switching enables support of GPRS multi-slot operation. The combination of an EGSM900 PA block, a DCS1800/PCS1900 PA block, impedance-matching circuitry allow for 50 ohm input and output and bias control circuitry.
