1 / 15 page TRF1600 www.ti.com SPAS094A – FEBRUARY 2010 – REVISED MAY 2011 TRUE RMS RF POWER DETECTOR Check for Samples: TRF1600 1 FEATURES • Operating Temperature Range: –20ºC to 85ºC • RF True RMS Power Detector • Small 2-mm x 2-mm QFN 6 Pin Package • RMS to DC Conversion Up to 2 GHz • Waveform and Modulation Independent APPLICATIONS (CW, GSM, WCDMA, TDMA, HSUPA) • Cellular Handsets (GSM, CDMA, TDMA) • Linear-In-dB Output • Power Amplifier Control Loops • Input Dynamic Range of 28 dB • Transmitter Power Measurement and Control ( –29 dBm to –1 dBm) • External Input Pin • 6.7-mA Typical Operating Current • 5- µA Maximum Shutdown Current DESCRIPTION The TRF1600 is a true RMS power detector with a 28-dB dynamic input range and a linear-to-dB DC output. It is intended for use in wireless handheld devices such as cell phones and PDAs to measure and control PA output power accurately independent of the modulation scheme. The device is designed to operate off of a lithium-ion battery (2.7 V to 5.5 V, 6 V tolerant) or a regulated supply. A low input signal at the enable pin puts the device in shut-down mode and supply current consumption is reduced to <5 µA. When asserted high the device enters active mode and outputs a DC voltage proportional to the RMS value of the input power expressed in dBm. Table 1.
