5–35–55 –15 TC = 25°C 4-CARRIER WCDMA CW 3-CARRIER CDMA2K TYPICAL APPLICATION FEATURES DESCRIPTION 40MHz to 10GHz RMS Power Detector with 57dB Dynamic Range The LTC®5582 is a 40MHz to 10GHz RMS responding power detector . It is capable of accurate power measure- ment of an AC signal with wide dynamic range, from –60dBm to 2dBm depending on frequency. The power of the AC signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale, independent of the crest factor of the input signal wave - forms. The L TC5582 is suitable for precision RF power measurement and level control for a wide variety of RF standards, including L TE, WiMAX, W-CDMA, CDMA2000, TD-SCDMA, and EDGE. The DC output is buffered with a low output impedance amplifier capable of driving a high capacitance load. Consult factory for more information. The part is packaged in a 10-lead 3mm × 3mm DFN. It is pin-to-pin compatible with the L T5570. All registered trademarks and trademarks are the property of their respective owners.

Note 5: Operation over a wider frequency range is possible with reduced performance. Consult the factory for information and assistance. Note 6: The linearity error is calculated by the difference between the incremental slope of the output and the average output slope from –50dBm to –5dBm for frequencies up to 5.8GHz, and –25dBm to –5dBm for 8GHz and 10GHz. The dynamic range is defined as the range over which the linearity error is within ±1dB.

Rev. DFor more information www.analog.com PIN FUNCTIONS VCC (Pin 1): Power Supply Pin. Typical current consump- tion is 41.6mA at room temperature. This pin should be externally bypassed with 1nF and 1µF chip capacitors. IN+, IN– (Pins 2, 4): Differential Input Signal Pins. Either one can be driven with a single-ended signal while the other is AC-coupled to ground. These pins can also be driven with a differential signal. The pins are internally biased to 1.585V and should be DC blocked externally. The differential impedance is typically 400Ω. The impedance of each pin to the DEC pin is 200Ω. DEC (Pin 3): Input Common Mode Decoupling Pin. This pin is internally biased to 1.585V and connected to an on- chip 50pF capacitor to ground. The impedance between DEC and IN+ (or IN–) is 200Ω. The pin can be connected to the center tap of an external balun when terminated differentially. The pin can be floating or connected to ground via an AC-decoupling capacitor when driven either in single-ended or differential input configuration. GND (Pin 5, Exposed Pad Pin 11): Circuit Ground Return for the Entire IC. This must be soldered to the printed circuit board ground plane. OUT (Pin 6): DC Output Pin. The output impedance is mainly determined by an internal 100Ω series resistance which provides protection if the output is shorted to ground. RT2 (Pin 7): Optional Control Pin for 2nd-Order Output Temperature Compensation. Connect this pin to ground to disable it. The output voltage will decrease with respect to the room temperature (25°C) by connecting it to ground via an off-chip resistor when the ambient temperature is either higher or lower . RT1 (Pin 8): Optional Control Pin for 1st-Order Output Temperature Compensation. Connect this pin to ground to disable it. The output voltage will increase inversely proportional to ambient temperature. EN (Pin 9): Enable Pin. An applied voltage above 1V will activate the bias for the IC. For an applied voltage below 0.4V , the circuits will be shut down (disabled) with a reduc- tion in power supply current. If the enable function is not required, then this pin can be connected to V CC. Typical enable pin input current is 100μA for EN = 3.3V . Note that at no time should the Enable pin voltage be allowed to exceed VCC by more than 0.3V . FL TR (Pin 10): Connection for an External Filtering Capaci- tor C3. A minimum of 8nF capacitance is required for stable AC average power measurement. This capacitor should be connected to VCC.
