The LTC5597 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 70GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation and power control applications. The DC output voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 28.5mV/dB logarithmic slope over a 35dB dynamic range with typically better than ?1dB accuracy. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12dB, and waveforms that exhibit a significant variation of the crest factor during measurement. To achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a capacitor connected between the FLTR and OUT pins. The enable interface switches the device between active measurement mode and a low power shutdown mode.Applications Point-to-Point Microwave Links SATCOM Instrumentation and Measurement Equipment Military Radios 5G, LTE, WiFi, Wireless Networks RMS Power Measurement Receive and Transmit Gain Control RF PA Transmit Power Control

The LTC1864/LTC1865 are 16-bit A/D converters that are offered in MSOP and SO-8 packages and operate on a single 5V supply. At 250ksps, the supply current is only 850?A. The supply current drops at lower speeds because the LTC1864/LTC1865 automatically power down between conversions. These 16-bit switched capacitor successive approximation ADCs include sample-and-holds. The LTC1864 has a differential analog input with an adjustable reference pin. The LTC1865 offers a software-selectable 2-channel MUX and an adjustable reference pin on the MSOP version.The 3-wire, serial I/O, small MSOP or SO-8 package and extremely high sample rate-to-power ratio make these ADCs ideal choices for compact, low power, high speed systems.These ADCs can be used in ratiometric applications or with external references. The high impedance analog inputs and the ability to operate with reduced spans down to 1V full scale, allow direct connection to signal sources in many applications, eliminating the need for external gain stages.Applications High Speed Data Acquisition Portable or Compact Instrumentation Low Power Battery-Operated Instrumentation Isolated and/or Remote Data Acquisition

The LTC3406B is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V and 1.8V. Supply current with no load is 300?A and drops to <1?A in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406B ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.

The LT1738 is a switching regulator controller designed to lower conducted and radiated electromagnetic interference (EMI). Ultralow noise and EMI are achieved by controlling the voltage and current slew rates of an external N-channel MOSFET switch. Current and voltage slew rates can be independently set to optimize harmonic content of the switching waveforms vs efficiency. The LT1738 can reduce high frequency harmonic power by as much as 40dB with only minor losses in efficiency. The LT1738 utilizes a current mode architecture optimized for single switch topologies such as boost, flyback and Cuk. The IC includes gate drive and all necessary oscillator, control and protection circuitry. Unique error amp circuitry can regulate both positive and negative voltages. The internal oscillator may be synchronized to an external clock for more accurate placement of switching harmonics. Protection features include gate drive lockout for low VIN, soft-start, output current limit, short-circuit current limit-ing, gate drive overvoltage clamp and input supply undervoltage lockout.Applications Power Supplies for Noise Sensitive Communication Equipment EMI Compliant Offline Power Supplies Precision Instrumentation Systems Isolated Supplies for Industrial Automation Medical Instruments Data Acquisition Systems

Demonstration circuit 516A-B is a low output voltage, synchronous boost converter featuring the LTC3424. The LTC3424 is ideal for applications that require an output voltage between 1.5V to 2.6V from a single alkaline or NiCd/NiMH cell. A bias voltage (VDD) of 2.7V to 5.5V is required to power the internal circuitry. The input voltage (VIN) range is 1V to 1.6V, but once up and running, the device can operate with an input voltage as low as 0.5V. The output voltage is set at 1.8V. For a 1V minimum battery voltage, the LTC3424 can provide 600mA.
