The ADL5902 is a true rms responding power detector that hasa 65 dB measurement range when driven with a single-ended 50 Ω source. This feature makes the ADL5902 frequencyversatile by eliminating the need for a balun or any other form of external input tuning for operation up to 9 GHz.The ADL5902 provides a solution in a variety of high frequencysystems requiring an accurate measurement of signal power. Requiring only a single supply of 5 V and a few capacitors, it is easy to use and capable of being driven single-ended or with abalun for differential input drive. The ADL5902 can operate from 50 MHz to 9 GHz and can accept inputs from −62 dBm to at least +3 dBm with large crest factors, such as GSM, CDMA,W-CDMA, TD-SCDMA, WiMAX, and LTE modulated signals.The ADL5902 can determine the true power of a high frequency signal having a complex low frequency modulation envelope or can be used as a simple low frequency rmsvoltmeter. Used as a power measurement device, VOUT isconnected to VSET. The output is then proportional to thelogarithm of the rms value of the input. In other words, thereading is presented directly in decibels and is scaled 1.06 V per decade, or 53 mV/dB; other slopes are easily arranged. In controller mode, the voltage applied to VSET determines thepower level required at the input to null the deviation from the set point. The output buffer can provide high load currents.The ADL5902 has 1.5 mW power consumption when powereddown by a logic high applied to the PWDN pin. It powers up within approximately 5 μs to its nominal operating current of 73 mA at 25°C. The ADL5902 is supplied in a 4 mm × 4 mm,16-lead LFCSP for operation over the wide temperature rangeof −40°C to +125°C.The ADL5902 is also pin-compatible with the AD8363, 50 dBdynamic range TruPwr™ detector. This feature allows the designer to create one circuit layout for projects requiring different dynamic ranges. A fully populated RoHS-compliant evaluation board is available.Applications Power amplifier linearization/control loops Transmitter power controls Transmitter signal strength indication (TSSI) RF instrumentation

The ADRF6702 provides a quadrature modulator and synthesizer solution within a small 6 mm × 6 mm footprint while requiring minimal external components.The ADRF6702 is designed for RF outputs from 1200 MHz to 2400 MHz. The low phase noise VCO and high performance quadrature modulator make the ADRF6702 suitable for next generation communication systems requiring high signal dynamic range and linearity. The integration of the IQ modulator, PLL, and VCO provides for significant board savings and reduces the BOM and design complexity.The integrated fractional-N PLL/synthesizer generates a 2× fLO input to the IQ modulator. The phase detector together with an external loop filter is used to control the VCO output. The VCO output is applied to a quadrature divider. To reduce spurious components, a sigma-delta (Σ-Δ) modulator controls the programmable PLL divider.The IQ modulator has wideband differential I and Q inputs, which support baseband as well as complex IF architectures. The single-ended modulator output is designed to drive a 50 Ω load impedance and can be disabled.The ADRF6702 is fabricated using an advanced silicon-germanium BiCMOS process. It is available in a 40-lead, exposed-paddle, Pb-free, 6 mm × 6 mm LFCSP package. Performance is specified from −40°C to +85°C. A lead-free evaluation board is available.APPLICATIONS Cellular communications systems        GSM/EDGE, CDMA2000, W-CDMA, TD-SCDMA, LTE Broadband wireless access systems Satellite modems
