Product Description
The RF7182 is a dual band (GSM850/PCS1900 or EGSM900/DCS1800)
GSM/GPRS Class 12 compliant transmit module with two symmetrical receive
ports. This transmit module builds upon RFMD’s leading power amplifier with Pow-
erStar® integrated power control technology, pHEMT switch technology, and inte-
grated transmit filtering for best-in-class harmonic performance. The results are
high performance, a reduced solution size, and ease of implementation. The device
is designed for use as the final portion of the transmitter section in a
GSM900/DCS1800 handset and eliminates the need for PA-to-antenna switch
module matching network.
The RF7182 features RFMD’s latest integrated power-flattening circuit, which signif-
icantly reduces current and power variation into load mismatch. The RF7182 also
integrates an ESD filter to provide excellent ESD protection at the antenna port. The
RF7182 is designed to provide maximum efficiency at rated POUT.

Proposed
RF7182
The RF7182 has an integrated power flattening circuit that reduces the amount of current variation when a mismatch is presented to the output
of the PA. When a mismatch is presented to the output of the PA, its output impedance is varied and could present a load that will increase out-
put power. As the output power increases, so does current consumption. The current consumption can become very high if not monitored and
limited. The power flattening circuit is integrated onto the CMOS controller and requires no input from the user.
Into a mismatch, the current varies as the phase changes. The power flattening circuit monitors current through an internal sense resistor. As the
current changes, the loop is adjusted in order to maintain current. The result is flatter power and reduced current into mismatch. The tran-
seiver/baseband to regulate the ramping signal as the supply voltage decreases. The internal circuit monitors the supply voltage and adjusts the
ramping signal such that the switching spectrum is minimally impacted.
The RF7182 also incorporates a VBATT tracking feature that eliminates the need for the transceiver/baseband to regulate the ramping signal as
the supply voltage decreases. The internal circuit monitors the supply voltage and adjusts the ramping signal such that the switching spectrum is
minimally impacted.
