The ADMV8818-EP is a fully monolithic microwave integrated circuit (MMIC) that features a digitally selectable frequency of operation. The device features four independently controlled high-pass filters (HPFs) and four independently controlled low-pass filters (LPFs) that span the 2 GHz to 18 GHz frequency range.The flexible architecture of the ADMV8818-EP allows the 3 dB cutoff frequency (f3dB) of the high-pass and low-pass filters to be controlled independently to generate up to 4 GHz of bandwidth. The digital logic control on each filter is 4 bits wide (16 states) and controls the on-chip reactive elements to adjust the f3dB. The typical insertion loss is 9 dB, and the wideband rejection is 35 dB, which is ideally suited for minimizing system harmonics.This tunable filter can be used as a smaller alternative to large switched filter banks and cavity tuned filters, and this device provides a dynamically adjustable solution in advanced communications applications.APPLICATIONSTest and measurement equipment Military radar, electronic warfare, and electronic countermeasures Satellite communications and space Industrial and medical equipment

DC1620A-L: Demo Board for LTC2140-14 14-Bit, 25Msps Low Power Dual ADCs.

The LTC5564 is a precision, RF power detector for applications in the 600MHz to 15GHz frequency range. The LTC5564 operates with input power levels from ?24dBm to 16dBm.A temperature compensated Schottky diode peak detector, gain-selectable operational amplifier, and fast comparator are combined in a small 16-lead 3mm ? 3mm QFN package.The RF input signal is peak detected and then sensed by both a comparator and amplifier. The comparator provides a 9ns response time to input levels exceeding VREF along with a latch enable/disable function. The gain selectable operational amplifier provides a 350V/?s slew rate and 75MHz of demodulation bandwidth to the analog output.VOUTADJ and VREF pins allow for the adjustment of VOUT offset and VCOMP switch point voltages, respectively.Applications RF Signal Presence Detectors for: 802.11a, 802.11b,?802.11g, 802.15, Optical Data Links, Wireless Data?Modems, Wireless and Cable Infrastructure 5.8GHz ISM Band Radios MMDS Microwave Links PA Power Supply Envelope Tracking Control Fast Alarm RF Power Monitor Envelope Detector Ultra-Wideband Radio Radar Detector

Demonstration circuit 1678A features the LTC2654 Quad 16-bit/12-bit DAC. The LTC2654 is a family of 16-bit/12-bit rail-to-rail DACs with integrated 10ppm/°C maximum reference. The LTC2654 advances performance standards for output drive, crosstalk and load regulation in single supply, voltage-output multiple DACs.

The LTC2654 is a family of quad 16-/12-bit rail-to-rail DACs with integrated 10ppm/?C maximum reference . The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic. The LTC2654-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The LTC2654-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage. These DACs communicate via a SPI/MICROWIRE? compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2654 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale. If PORSEL is tied to VCC, the DACs reset to mid-scale.Applications Mobile Communications Process Control and Industrial Automation Instrumentation Automatic Test Equipment Automotive
