The RF signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale. The wide linear dynamic range is achieved by measuring the RF signal using cascaded RF limiters and RF detectors. Their outputs are summed to generate an accurate linear DC voltage proportional to the input RF signal in m. The LT558 delivers superior temperature stable output (within ± over full temperature range) from 4MHz to.8ghz. The output is buffered with a low impedance driver., LT, LTC and LTM are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners.

7 LT558 PIN FUNCTIONS ENBL (Pin ): Enable Pin. An applied voltage above V will activate the bias for the IC. For an applied voltage below.v, the circuits will be shut down (disabled) with a corresponding reduction in power supply current. If the enable function is not required, then this pin can be connected to V CC. Typical enable pin input currents are μa for EN = V and μa for EN = 5V, respectively. Note that at no time should the ENBL pin voltage be allowed to exceed V CC by more than.v. IN + (Pin ): RF Input Pin. The pin is internally biased to V CC.5V and should be DC blocked externally. The input is connected via internal 94Ω resistor to the IN pin which should be connected to ground with an ac-decoupling capacitor. IN (Pin ): AC Ground Pin. The pin is internally biased to V CC.5V and coupled to ground via internal pf capacitor. This pin should be connected to ground with an external ac-decoupling capacitor for low frequency operation. GND (Pin 4, Exposed Pad Pin 9): Circuit Ground Return for the entire IC. This pin must be soldered to the printed circuit board ground plane. V CC (Pin 5): Power Supply Pin. This pin should be decoupled using pf and.μf capacitors. CAP, CAP + (Pins 6, 7): Optional Filter Capacitor Pins. These pins are internally connected to the detector outputs in front of the output buffer amplifier. An external low-pass filtering can be formed by connecting a capacitor to Vcc from each pin for filtering a low frequency modulation signal. See the Applications Information section for detail.

8 LT558 APPLICATIONS INFORMATION The LT558 is a 4MHz to.8 GHz logarithmic RF power detector. It consists of cascaded limiting amplifi ers and RF detectors. The output currents from every RF detector are combined and low-pass filtered before applied to the output buffer amplifier. As a result, the final DC output voltage approximates the logarithm of the amplitude of the input signal. The LT558 is able to accurately measure an RF signal over a 7 dynamic range ( 68m to m at.ghz) with 5Ω single-ended input impedance. The slope of linear to log transfer function is about 7.7mV/ at.ghz. Within the linear dynamic range, very stable output is achieved over the full temperature range from 4 C to 85 C and over the full operating frequency range from 4MHz to.8ghz. The absolute variation over temperature is typically within ± over 65 dynamic range at.ghz. RF INPUT The simplified schematic of the input circuit is shown in Figure. The IN + and IN pins are internally biased to V CC.5V. The IN pin is internally coupled to ground via pf capacitor. An external capacitor of nf is needed to connect this pin to ground for low frequency operation. The impedance between IN + and IN is about 94Ω. The RF input pin IN + should be DC blocked when connected to ground or other matching components. A 56Ω resistor (R) connected to ground will provide better than input return loss over the operating frequency range up to.5ghz. At higher operating frequency, additional LC matching elements are needed for a proper impedance matching to a 5Ω source as shown in Figure. Refer to Figure 6 for the circuit schematic of the input matching network. The input impedance vs frequency of the RF input port IN + is detailed in Table. Table.

9 APPLICATIONS INFORMATION OUTPUT INTERFACE The output interface of the LT558 is shown in Figure. This output buffer circuit can source ma current to the load and sink μa current from the load. The smallsignal output bandwidth is approximately 4MHz when the output is resistively terminated or open. The full-scaled % to 9% rise and fall times are ns and 8nS, respectively.

When it is disabled, the output impedance is about 9.5kΩ referenced to ground. EXTERNAL FILTERING AT CAP +, CAP The CAP + and CAP Pins are internally biased at V CC.6V via a Ω resistor from voltage supply V CC as shown in Figure. These two pins are connected to the differential outputs of the internal RF detector cells. In combination with the pf in parallel, a low-pass filter is formed with corner frequency of MHz. The high frequency rectified signals (particularly second-order harmonic of the RF signal) from the detector cells are filtered and then the DC output is amplified by the output buffer amplifier. In some applications, the LT558 may be used to measure a modulated RF signal with low frequency AM content (lower than MHz), a large modulation signal may be present at these two pins due to insufficient low-pass filtering, resulting in output voltage fl uctuation at the LT558 s output. Its DC content may also vary depending upon the modulation frequency. To assure stable DC output of the LT558, external capacitors C6 and C9 can be connected from CAP + and CAP to V CC to filter out this low frequency AM modulation signal. Assume the modulation frequency of the RF signal is f MOD, the capacitor value in Farads of C6 and C9 can be chosen by the following formula: C6 (or C9) /(π f MOD ) Do not connect these two filtering capacitors to ground or any other low voltage reference at any time to avoid an abnormal start-up condition TIME (μs) 558 F4 Figure 4. Simplifi ed Circuit Schematic of the Output Interface 558f 9

10 LT558 APPLICATIONS INFORMATION ENBL (ENABLE) PIN OPERATION A simplified circuit schematic of the ENBL Pin is shown in Figure 5. The enable voltage necessary to turn on the LT558 is V. The current drawn by the ENBL pin varies with the voltage applied at the pin. When the ENBL voltage is V, the ENBL current is typically μa. When the ENBL voltage is 5V, the ENBL current is increased to μa. To disable or turn off the chip, this voltage should be below.v. It is important that the voltage applied to the ENBL pin should never exceed V CC by more than.v. Otherwise, the supply current may be sourced through the upper ESD protection diode connected at the ENBL pin. Under no circumstances should voltage be applied to the ENBL Pin before the supply voltage is applied to the V CC pin. If this occurs, damage to the IC may result. V CC ENBL 4k 4k 558 F5 Figure 5.
