Product Description
The RF4180 is a dual band (GSM900/DCS1800) transmit module with two sym-
metrical receive ports and GSM/GPRS Class 12 compliant. This transmit module
builds upon RFMD’s leading power amplifier with PowerStar® integrated power
control technology, pHEMT switch technology and integrated transmit filtering for
best-in-class harmonics. This results in high performance, a reduced solution size,
and the ease of implementation simplifies transmitter design. The device is
designed for use as the final portion of the transmit in GSM900/DCS1800 and
eliminates the need for PA to antenna switch module matching. The device provides
50Ω matched input and output ports with no matching required.
The RF4180 features RFMD’s latest integrated power flattening circuit, which signif-
icantly reduces current and power variation into load mismatch. The RF4180 also
integrates an ESD filter to provide excellent ESD protection at the antenna port. The
RF4180 is designed to provide maximum efficiency at rated P_OUT.
