The ADL8150 is a self biased gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), heterojunction bipolar transistor (HBT), low phase noise amplifier that operates from 6 GHz to 14 GHz. The amplifier provides 12 dB of typical signal gain, 18 dBm output power at 1 dB gain compression (OP1dB), and a typical output third-order intercept (OIP3) of 30 dBm. The amplifier requires 74 mA from a 5 V collector supply voltage. The ADL8150 also features inputs and outputs (I/Os) that are internally matched to 50 ?, and facilitates integration into multichip modules (MCMs). Note that throughout the data sheet, multifunction pins, such as RFOUT/VCC, are referred to either by the entire pin name or by a single function of the pin, for example, RFOUT, when only that function is relevant.Applications Military and space Test instrumentation Communications

The ADRF5549 is a dual-channel, integrated, RF front-end multichip module designed for time division duplexing (TDD) applications that operates from 1.8 GHz to 2.8 GHz. The ADRF5549 is configured in dual channels with a cascading, two-stage, low noise amplifier (LNA) and a high power, silicon single-pole, double-throw (SPDT) switch.In high gain mode, the cascaded two-stage LNA and switch offer a low noise figure of 1.4 dB and a high gain of 35 dB with an output third-order intercept point (OIP3) of 32 dBm typical.In low gain mode, one stage of the two-stage LNA is in bypass mode providing 17 dB of gain at a lower current of 35 mA. In power-down mode, the LNAs are turned off, and the device draws 12 mA.In transmit operation, when RF inputs are connected to a termination pin (TERM-ChA or TERM-ChB), the switch provides a low insertion loss of 0.6 dB and handles a long-term evolution (LTE) full lifetime average (9 dB peak to average ratio (PAR)) of 40 dBm and 43 dBm for a 9 dB PAR LTE single event (ApplicationsWireless InfrastructureTDD massive multiple input and multiple output (MIMO) and active antenna systemsTDD-based communication systems

This TI Verified Design implements a comparator with hysteresis. Comparators are used to differentiate between two different signal levels. For example: a comparator may differentiate between an over temperature and normal temperature condition. Noise or signal variation at the comparison threshold will cause multiple transitions. Hysteresis sets an upper and lower threshold to eliminate the multiple transitions caused by noise.

The ADMV1013 is a wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 24 GHz to 44 GHz radio frequency (RF) range.The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from baseband in-phase quadrature (I/Q) input signals, as well as single-sideband (SSB) upconversion from complex intermediate frequency (IF) inputs. The baseband I/Q input path can be disabled and modulated complex IF signals, anywhere from 0.8 GHz to 6.0 GHz, can be inserted in the IF path and upconverted to 24 GHz to 44 GHz while suppressing the unwanted sideband by typically better than 26 dBc. The serial port interface (SPI) allows adjustment of the quadrature phase and mixer gate voltage to allow optimum sideband suppression and local oscillator (LO) nulling. In addition, the SPI interface allows powering down the output envelope detector to reduce power consumption.The ADMV1013 upconverter comes in a 40-terminal land grid array package (LGA) package. The ADMV1013 operates over the ?40?C to +85?C case temperature range.Applications Point to point microwave radios Radar, electronic warfare systems Instrumentation, automatic test equipment (ATE)

Demonstration circuit DC1708A is a dual-output regulator focused specifically for DDR memory power applications. It is built based on the LTC3634, a high voltage dualchannel, controlled on-time monolithic synchronous buck regulator. The DC1708A has an input voltage range of 3.6V to 15V. The output voltage of the first channel, VDDQ, of the DC1708A has three fixed voltage settings: 1.5V, 1.8V and 2.5V, and is capable of delivering up to 3A of output current. The second channel, VTT, is set to regulate to half the voltage on the VDDQIN pin, which can be either the channel 1 output or an external reference voltage. It can source or sink a maximum of 3A of output current. The LTC3634 also provides a 10mA buffered output of half VDDQIN – VTTR, which is used to provide the reference voltage needed for DDR applications. With the use of a timing resistor, the DC1708A can have its operating frequency programmed from 500kHz to 4MHz. Additionally the DC1708A can be easily synchronized to an external clock, due to an internal phase-locked loop, within this same frequency range. The DC1708A VDDQ output can operate in either Burst Mode® operation or forced continuous mode. In Burst Mode operation, which is the preferred mode of low load current operation, the DC supply current is typically only 1.3mA (both channels) at no load (sleep mode), and less than 15µA in shutdown. In Burst Mode operation or continuous mode operation, the DC1708A is a very efficient circuit at high load currents: over 80% for either channel. The LTC3634 is also capable of 90° or 180° out-of-phase operation, and can allow its output to track an external voltage, either coincidentally or ratiometrically. The LTC3634 comes in a 28-pin QFN package, featuring an exposed pad on the bottom-side of the IC for better thermal performance. All of these features make the DC1708A an ideal circuit for powering DDR memory applications.
